The Pin Function Controller module in the R-Car H3 ES2.0 differs from
ES1.x in many ways.
The goal is twofold:
1. Support both the ES1.x and ES2.0 SoC revisions in a single binary
for now,
2. Make it clear which code supports ES1.x, so it can easily be
identified and removed later, when production SoCs are deemed
ubiquitous.
Hence this patch:
1. Extracts the support for R-Car H3 ES1.x into a separate file, as
the differences are quite large,
2. Adds code for detecting the SoC revision at runtime using the new
soc_device_match() API, and selecting pinctrl tables for the actual
SoC revision,
3. Replaces the core register and bitfield definitions by their
counterparts for R-Car H3 ES2.0.
The addition of pins, groups, and functions for the various on-chip
devices is left to subsequent patches.
The R-Car H3 ES2.0 register and bitfield definitions were extracted from
a patch in the BSP by Takeshi Kihara.

The sh-pfc pinctrl driver is currently handling SoC-specific
PFC hardware blocks on ARM64, ARM and SH architectures.
For older SoCs using SH cores and some 32-bit ARM SoCs the PFC
hardware also provides GPIO functionality. On the majority of
32-bit ARM SoCs from Renesas and so far all ARM64 SoCs the GPIO
feature is provided by separate hardware blocks.
So far GPIO support in the PFC driver has been compiled-in for
the majority of the SoCs, but with this patch applied the SoCs
with PFC support may select from one of the following:
- CONFIG_PINCTRL_SH_PFC - Used if PFC lacks GPIO hardware
- CONFIG_PINCTRL_SH_PFC_GPIO - Used if PFC includes GPIO support
This patch results in the following changes:
- The GPIO functionality is only compiled-in on relevant SoCs
- The number of lines of code is reduced
Build tested using the following configurations:
- r8a7795 -> CONFIG_PINCTRL_SH_PFC_GPIO=n -> OK (ARM64)
- r8a7790 -> CONFIG_PINCTRL_SH_PFC_GPIO=n -> OK (ARM)
- r8a7790 + r8a7740 -> CONFIG_PINCTRL_SH_PFC_GPIO=y -> OK (ARM)
- r8a7740 -> CONFIG_PINCTRL_SH_PFC_GPIO=y -> OK (ARM)
- sh7751 -> CONFIG_PINCTRL_SH_PFC=n -> OK (SH rts7751r2d1)
- sh7724 -> CONFIG_PINCTRL_SH_PFC_GPIO=y -> OK (SH ecovec24)

Add PFC support for the R8A7794 SoC including pin groups for some
on-chip devices such as ETH, I2C, INTC, MSIOF, QSPI, [H]SCIF...
Sergei: squashed together several patches, fixed the MLB_CLK typo,
added IRQ4.. IRQ9 pin groups, fixed IRQn comments, added ETH B pin
group names, removed stray new line and fixed typos in the comments
in the pinmux_config_regs[] initializer, removed the platform device
ID, took into account limited number of signals in the GPIO1/5/6
controllers, added reasonable and removed unreasonable
copyrights, modified the bindings document, renamed, added changelog.
Changes in version 5:
- resolved rejects, refreshed the patch;
- added Laurent Pinchart's ACK.
Changes in version 4:
- reused the PORT_GP_26() macro to #define PORT_GP_28().
Changes in version 3:
- removed the platform device ID;
- added PORT_GP_26() and PORT_GP_28() macros, used them for GPIO1/5/6 in the
CPU_ALL_PORT() macro.
Changes in version 2:
- rebased the patch.
