ARM: OMAP2+: PRM: create PRM reset source API for the watchdog timer driver
The OMAP watchdog timer driver needs to determine what caused the SoC to reset for its GETBOOTSTATUS ioctl. So, define a set of standard reset sources across OMAP SoCs. For OMAP2xxx, 3xxx, and 4xxx SoCs, define mappings from the SoC-specific reset source register bits to the standardized reset source IDs. Create SoC-specific PRM functions that read the appropriate per-SoC register and use the mapping to return the standardized reset bits. Register the SoC-specific PRM functions with the common PRM code via prm_register(). Create a function in the common PRM code, prm_read_reset_sources(), that calls the SoC-specific function, registered during boot. This patch does not yet handle some SoCs, such as AM33xx. Those SoCs were not handled by the code this will replace. Signed-off-by: Paul Walmsley <paul@pwsan.com>
