pinctrl: aspeed: Read and write bits in LPC and GFX controllers The System Control Unit IP block in the Aspeed SoCs is typically where the pinmux configuration is found, but not always. A number of pins depend on state in one of LPC Host Control (LHC) or SoC Display Controller (GFX) IP blocks, so the Aspeed pinmux drivers should have the means to adjust these as necessary. We use syscon to cast a regmap over the GFX and LPC blocks, which is used as an arbitration layer between the relevant driver and the pinctrl subsystem. The regmaps are then exposed to the SoC-specific pinctrl drivers by phandles in the devicetree, and are selected during a mux request by querying a new 'ip' member in struct aspeed_sig_desc.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Split out pinmux from general pinctrl ASPEED have completely rearranged the System Control Unit register layout with the AST2600. The existing code took advantage of the fact that the AST2400 and AST2500 had layouts that were similar enough to have little impact on the pinmux infrastructure (though there is a wart with read-modify-write vs write-1-clear semantics of the hardware strapping registers between the two). Given that any similarity has been thrown out with the AST2600, separate out the function applying an expression state to be driver-specific. With it, extract out the pinmux macro jungle to its own header and implementation so the pieces can be composed without dependency cycles.

In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers.

As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol.

However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Read and write bits in LPC and GFX controllers The System Control Unit IP block in the Aspeed SoCs is typically where the pinmux configuration is found, but not always. A number of pins depend on state in one of LPC Host Control (LHC) or SoC Display Controller (GFX) IP blocks, so the Aspeed pinmux drivers should have the means to adjust these as necessary. We use syscon to cast a regmap over the GFX and LPC blocks, which is used as an arbitration layer between the relevant driver and the pinctrl subsystem. The regmaps are then exposed to the SoC-specific pinctrl drivers by phandles in the devicetree, and are selected during a mux request by querying a new 'ip' member in struct aspeed_sig_desc.

pinctrl: aspeed-g5: Fix pin association of SPI1 function The SPI1 function was associated with the wrong pins: The functions that those pins provide is either an SPI debug or passthrough function coupled to SPI1. Make the SPI1 mux function configure the relevant pins and associate new SPI1DEBUG and SPI1PASSTHRU functions with the pins that were already defined. The notation used in the datasheet's multi-function pin table for the SoC is often creative: in this case the SYS* signals are enabled by a single bit, which is nothing unusual on its own, but in this case the bit was also participating in a multi-bit bitfield and therefore represented multiple functions.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication.

pinctrl: aspeed: Read and write bits in LPC and GFX controllers The System Control Unit IP block in the Aspeed SoCs is typically where the pinmux configuration is found, but not always. A number of pins depend on state in one of LPC Host Control (LHC) or SoC Display Controller (GFX) IP blocks, so the Aspeed pinmux drivers should have the means to adjust these as necessary. We use syscon to cast a regmap over the GFX and LPC blocks, which is used as an arbitration layer between the relevant driver and the pinctrl subsystem. The regmaps are then exposed to the SoC-specific pinctrl drivers by phandles in the devicetree, and are selected during a mux request by querying a new 'ip' member in struct aspeed_sig_desc.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers.

As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers. For a more practical test I've inspected the diff of the content of the pinctrl debugfs entries before and after the patch under qemu; all pins, functions and groups match.

pinctrl: aspeed: Add multiple pin group support for functions The AST2400 and AST2500 SoCs only exposed one pin group per function. Lone pin groups drove some implementation simplifications in the ASPEED pinmux infrastructure that is now invalid for the AST2600, which supports multiple groups per function for some functions on the chip (SMBus Alert pins and UARTs among others). This patch reworks the macro jungle to enable support for multiple pin groups. In the process we inflict some collateral damage on the existing AST2400 and AST2500 drivers, but the rework is mostly a relatively straight-forward, automated transform of adding the pin name as an argument to some macro calls and implementing wrappers to paper over groups in the cases where there aren't multiple. As previously documented, the macro infrastructure exposes mux configuration as symbols in the source file which are used to detect accidental duplication. Previously these symbols were named in terms of the signal for a given expression. As the AST2600 supports multiple pin groups for a function, the signal name on its own is no-longer unique, and we must switch to the (signal, group) tuple. However, this means that we can no-longer derive the signal expression symbol name from the signal name alone, which among other cases, impacts the operation of the PIN_DECL_x() macros. To fix that and avoid requiring we awkwardly provide the associated group name for every signal for every PIN_DECL_x() invocation, instead opportunistically alias the name of the signal expression symbol from the unique (signal, group) tuple to the also unique (pin, signal) tuple, then reference the alias symbol in the tables generated by PIN_DECL_x(). This way we do not require extra group parameters for PIN_DECL_x() as the pin name was already provided as an argument, and instead simply require that the pin name be provided to the expression declaration macros in order to generate the alias symbol. The patch implements the alias strategy and fixes up all the expression definition macro calls in the AST2400 and AST2500 drivers to account for pin groups. Given the implementation strategy has the property that compilation either fails or loudly warns for bad pin descriptions, this patch is theoretically tested by successfully compiling both affected drivers.

pinctrl: aspeed-g5: Fix pin association of SPI1 function The SPI1 function was associated with the wrong pins: The functions that those pins provide is either an SPI debug or passthrough function coupled to SPI1. Make the SPI1 mux function configure the relevant pins and associate new SPI1DEBUG and SPI1PASSTHRU functions with the pins that were already defined. The notation used in the datasheet's multi-function pin table for the SoC is often creative: in this case the SYS* signals are enabled by a single bit, which is nothing unusual on its own, but in this case the bit was also participating in a multi-bit bitfield and therefore represented multiple functions.

pinctrl: aspeed-g5: Fix pin association of SPI1 function The SPI1 function was associated with the wrong pins: The functions that those pins provide is either an SPI debug or passthrough function coupled to SPI1. Make the SPI1 mux function configure the relevant pins and associate new SPI1DEBUG and SPI1PASSTHRU functions with the pins that were already defined. The notation used in the datasheet's multi-function pin table for the SoC is often creative: in this case the SYS* signals are enabled by a single bit, which is nothing unusual on its own, but in this case the bit was also participating in a multi-bit bitfield and therefore represented multiple functions. This fact was overlooked in the original patch.

Make the SPI1 mux function configure the relevant pins and associate new SPI1DEBUG and SPI1PASSTHRU functions with the pins that were already defined. The notation used in the datasheet's multi-function pin table for the SoC is often creative: in this case the SYS* signals are enabled by a single bit, which is nothing unusual on its own, but in this case the bit was also participating in a multi-bit bitfield and therefore represented multiple functions.

Make the SPI1 mux function configure the relevant pins and associate new SPI1DEBUG and SPI1PASSTHRU functions with the pins that were already defined. The notation used in the datasheet's multi-function pin table for the SoC is often creative: in this case the SYS* signals are enabled by a single bit, which is nothing unusual on its own, but in this case the bit was also participating in a multi-bit bitfield and therefore represented multiple functions.

pinctrl: aspeed: Fix spurious mux failures on the AST2500 Commit 674fa8daa8c9 ("pinctrl: aspeed-g5: Delay acquisition of regmaps") was determined to be a partial fix to the problem of acquiring the LPC Host Controller and GFX regmaps: The AST2500 pin controller may need to fetch syscon regmaps during expression evaluation as well as when setting mux state. For example, this case is hit by attempting to export pins exposing the LPC Host Controller as GPIOs. An optional eval() hook is added to the Aspeed pinmux operation struct and called from aspeed_sig_expr_eval() if the pointer is set by the SoC-specific driver. This enables the AST2500 to perform the custom action of acquiring its regmap dependencies as required. John Wang tested the fix on an Inspur FP5280G2 machine (AST2500-based) where the issue was found, and I've booted the fix on Witherspoon (AST2500) and Palmetto (AST2400) machines, and poked at relevant pins under QEMU by forcing mux configurations via devmem before exporting GPIOs to exercise the driver.

pinctrl: aspeed: Fix spurious mux failures on the AST2500 Commit 674fa8daa8c9 ("pinctrl: aspeed-g5: Delay acquisition of regmaps") was determined to be a partial fix to the problem of acquiring the LPC Host Controller and GFX regmaps: The AST2500 pin controller may need to fetch syscon regmaps during expression evaluation as well as when setting mux state. For example, this case is hit by attempting to export pins exposing the LPC Host Controller as GPIOs. An optional eval() hook is added to the Aspeed pinmux operation struct and called from aspeed_sig_expr_eval() if the pointer is set by the SoC-specific driver. This enables the AST2500 to perform the custom action of acquiring its regmap dependencies as required. John Wang tested the fix on an Inspur FP5280G2 machine (AST2500-based) where the issue was found, and I've booted the fix on Witherspoon (AST2500) and Palmetto (AST2400) machines, and poked at relevant pins under QEMU by forcing mux configurations via devmem before exporting GPIOs to exercise the driver.

As such the GFX syscon is not yet registered during the pinctrl probe() and we get an -EPROBE_DEFER when we try to look it up, however we must not defer probing the pinctrl driver for the inability to mux some GFX-related functions. Switch to lazily grabbing the regmaps when they're first required by the mux configuration. This generates a bit of noise in the patch as we have to drop the `const` qualifier on arguments for several function prototypes, but has the benefit of working. I've smoke tested this for the ast2500-evb under qemu with a dummy graphics device. We now succeed in our attempts to configure the SoC's VPO pinmux function.

pinctrl: aspeed: Read and write bits in LPC and GFX controllers The System Control Unit IP block in the Aspeed SoCs is typically where the pinmux configuration is found, but not always. A number of pins depend on state in one of LPC Host Control (LHC) or SoC Display Controller (GFX) IP blocks, so the Aspeed pinmux drivers should have the means to adjust these as necessary. We use syscon to cast a regmap over the GFX and LPC blocks, which is used as an arbitration layer between the relevant driver and the pinctrl subsystem. The regmaps are then exposed to the SoC-specific pinctrl drivers by phandles in the devicetree, and are selected during a mux request by querying a new 'ip' member in struct aspeed_sig_desc.
