davinci: Encapsulate SoC-specific data in a structure Create a structure to encapsulate SoC-specific information. This will assist in generalizing code so it can be used by different SoCs that have similar hardware but with minor differences such as having a different base address. The idea is that the code for each SoC fills out a structure with the correct information. The board-specific code then calls the SoC init routine which in turn will call a common init routine that makes a copy of the structure, maps in I/O regions, etc. After initialization, code can get a pointer to the structure by calling davinci_get_soc_info(). Eventually, the common init routine will make a copy of all of the data pointed to by the structure so the original data can be made __init_data. That way the data for SoC's that aren't being used won't consume memory for the entire life of the kernel. The structure will be extended in subsequent patches but initially, it holds the map_desc structure for any I/O regions the SoC/board wants statically mapped. Signed-off-by: Mark A.

davinci: Move serial platform_device into SoC-specific files Currently, there is one set of platform_device and platform_data structures for all DaVinci SoCs. The differences in the data between the various SoCs is handled by davinci_serial_init() by checking the SoC type. However, as new SoCs appear, this routine will become more & more cluttered. To clean up the routine and make it easier to add support for new SoCs, move the platform_device and platform_data structures into the SoC-specific code and use the SoC infrastructure to provide access to the data. In the process, fix a bug where the wrong irq is used for uart2 of the dm646x. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

davinci: Move interrupt ctlr info to SoC infrastructure Use the SoC infrastructure to hold the interrupt controller information (i.e., base address, default priorities, interrupt controller type, and the number of IRQs). The interrupt controller base, although initially put in the soc_info structure's intc_base field, is eventually put in the global 'davinci_intc_base' so the low-level interrupt code can access it without a dereference. These changes enable the SoC default irq priorities to be put in the SoC-specific files, and the interrupt controller to be at any base address. Signed-off-by: Mark A.

Modify the edma_alloc_slot function to take an extra argument for the controller. Also update ASoC drivers to use API. ASoC changes Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> - Move queue related mappings to dm<soc>.c EDMA in DM355 and DM644x has two transfer controllers while DM646x has four transfer controllers. Moving the queue to tc mapping and queue priority mapping to dm<soc>.c will be helpful to probe these mappings from platform device so that the machine_is_* testing will be avoided. - add channel mapping logic Channel mapping logic is introduced in dm646x EDMA. This implies that there is no fixed association for a channel number to a parameter entry number. In other words, using the DMA channel mapping registers (DCHMAPn), a PaRAM entry can be mapped to any channel. While in the case of dm644x and dm355 there is a fixed mapping between the EDMA channel and Param entry number.

ASoC: davinci: fixes for multi-component Multi-component commit f0fba2ad broke a few things which this patch should fix. Tested on the DM355 EVM. I've been as careful as I can, but it would be good if those with access to other Davinci boards could test. -- The multi-component commit put the initialisation of snd_soc_dai.[capture|playback]_dma_data into snd_soc_dai_ops.hw_params of the McBSP, McASP & VCIF drivers (davinci-i2s.c, davinci-mcasp.c & davinci-vcif.c). The initialisation had to be moved from the probe function in these drivers because davinci_*_dai changed from snd_soc_dai to snd_soc_dai_driver. Unfortunately, the DMA params pointer is needed by davinci_pcm_open (in davinci-pcm.c) before hw_params is called. I have moved the initialisation to a new snd_soc_dai_ops.startup function in each of these drivers. This fix indicates that all platforms that use davinci-pcm must have been broken and need to test with this fix. -- The multi-component commit also changed the McBSP driver name from "davinci-asp" to "davinci-i2s" in davinci-i2s.c without updating the board level references to the driver name. This change is understandable, as there is a similarly named "davinci-mcasp" driver in davinci-mcasp.c. There is probably no 'correct' name for this driver. The DM6446 datasheet calls it the "ASP" and describes it as a "specialised McBSP". The DM355 datasheet calls it the "ASP" and describes it as a "specialised ASP". The DM365 datasheet calls it the "McBSP". Rather than fix this problem by reverting to "davinci-asp", I've elected to avoid future confusion with the "davinci-mcasp" driver by changing it to "davinci-mcbsp", which is also consistent with the names of the functions in the driver. There are other fixes required, so it was never going to be as simple as a revert anyway. -- The DM365 only has one McBSP port (of the McBSP platforms, only the DM355 has 2 ports), so I've changed the the id of the platform_device from 0 to -1. -- In davinci-evm.c, the DM6446 EVM can no longer share a snd_soc_dai_link structure with the DM355 EVM as they use different cpu DAI names (the DM355 has 2 ports and the EVM uses the second port, but the DM6446 only has 1 port). This also means that the 2 boards need different snd_soc_card structures. -- The codec_name entries in davinci-evm.c didn't match the i2c ids in the board files. I have only checked and fixed the details of the names used for the McBSP based platforms. Someone with a McASP based platform (eg DA8xx) should check the others.

To differentiate between this platforms venc_type/vpbe_type was passed as part of platform data which was incorrect. The correct way to differentiate to handle this case is by passing different platform names. This patch creates platform_device_id[] array supporting different platforms and assigns id_table to the platform driver, and finally in the probe gets the actual device by using platform_get_device_id() and gets the appropriate driver data for that platform.

ARM: davinci: dm644x: fix out range signal for ED Fix the video clock setting when custom timings are used with pclock <= 27MHz. Existing video clock selection uses PLL2 mode which results in a 54MHz clock whereas using the MXI mode results in a 27MHz clock (which is the one actually desired). This bug affects the Enhanced Definition (ED) support on DM644x. Without this patch, out-range signals errors are were observed on the TV when viewing ED. An out-of-range signal is often caused when the field rate is above the rate that the television will handle.

The correct way to differentiate to handle this case is by passing different platform names.

davinci: Encapsulate SoC-specific data in a structure Create a structure to encapsulate SoC-specific information. This will assist in generalizing code so it can be used by different SoCs that have similar hardware but with minor differences such as having a different base address. The idea is that the code for each SoC fills out a structure with the correct information. The board-specific code then calls the SoC init routine which in turn will call a common init routine that makes a copy of the structure, maps in I/O regions, etc. After initialization, code can get a pointer to the structure by calling davinci_get_soc_info(). Eventually, the common init routine will make a copy of all of the data pointed to by the structure so the original data can be made __init_data. That way the data for SoC's that aren't being used won't consume memory for the entire life of the kernel. The structure will be extended in subsequent patches but initially, it holds the map_desc structure for any I/O regions the SoC/board wants statically mapped. Signed-off-by: Mark A.

davinci: Support JTAG ID register at any address The Davinci cpu_is_davinci_*() macros use the SoC part number and variant retrieved from the JTAG ID register to determine the type of cpu that the kernel is running on. Currently, the code to read the JTAG ID register assumes that the register is always at the same base address. This isn't true on some newer SoCs. To solve this, have the SoC-specific code set the JTAG ID register base address in soc_info structure and add a 'cpu_id' member to it. 'cpu_id' will be used by the cpu_is_davinci_*() macros to match the cpu id. Also move the info used to identify the cpu type into the SoC-specific code to keep all SoC-specific code together.

davinci: Encapsulate SoC-specific data in a structure Create a structure to encapsulate SoC-specific information. This will assist in generalizing code so it can be used by different SoCs that have similar hardware but with minor differences such as having a different base address. The idea is that the code for each SoC fills out a structure with the correct information. The board-specific code then calls the SoC init routine which in turn will call a common init routine that makes a copy of the structure, maps in I/O regions, etc. After initialization, code can get a pointer to the structure by calling davinci_get_soc_info(). Eventually, the common init routine will make a copy of all of the data pointed to by the structure so the original data can be made __init_data. That way the data for SoC's that aren't being used won't consume memory for the entire life of the kernel. The structure will be extended in subsequent patches but initially, it holds the map_desc structure for any I/O regions the SoC/board wants statically mapped. Signed-off-by: Mark A.

davinci: Support JTAG ID register at any address The Davinci cpu_is_davinci_*() macros use the SoC part number and variant retrieved from the JTAG ID register to determine the type of cpu that the kernel is running on. Currently, the code to read the JTAG ID register assumes that the register is always at the same base address. This isn't true on some newer SoCs. To solve this, have the SoC-specific code set the JTAG ID register base address in soc_info structure and add a 'cpu_id' member to it. 'cpu_id' will be used by the cpu_is_davinci_*() macros to match the cpu id. Also move the info used to identify the cpu type into the SoC-specific code to keep all SoC-specific code together. The common code will read the JTAG ID register, search through an array of davinci_id structures to identify the cpu type. Once identified, it will set the 'cpu_id' member of the soc_info structure to the proper value and the cpu_is_davinci_*() macros will now work. Signed-off-by: Mark A.

While at it, also eliminate some duplicate sysmod register offset macros defined in code and place offset definitions at one place in davinci.h Signed-off-by: Manjunath Hadli <manjunath.hadli@ti.com> Acked-by: Arnd Bergmann <arnd@arndb.de> [nsekhar@ti.com: removed the addition of ifndef __ASSEMBLER__ in davinci.h, eliminate IO_ADDRESS() usage left out in dm646x.c, cleanup VPIF sysmodule register access as part of this patch and keep all sysmod offsets in davinci.h Also, convert the WARN_ON() on failure to setup sysmod base to BUG_ON()] Signed-off-by: Sekhar Nori <nsekhar@ti.com>

ARM: davinci: move davinci_clk_init() to init_time This moves the call of davinci_clk_init() from map_io to init_time for all boards. This is the proper place to init clocks. This is also done in preparation for moving to the common clock framework. dm646x is a special case because we need to handle different ref_clk rates depending on which board is being used. The clock init in this case is modified to set the rate before registering the clocks instead of using davinci_set_refclk_rate() to recalculate the entire clock tree after all of the clocks are registered. Also, the cpu_clks field is removed from struct davinci_soc_info since it is no longer needed. Signed-off-by: David Lechner <david@lechnology.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
