This has been implemented via TI only private driver APIs, as at least I am not aware of anybody else needing similar mechanism and it is pretty SoC architecture specific. - Dropped any powerdomain related data for now as it is not used for anything yet. - Added checks against illegal reset IDs. - Added checks for pdata validity during probe. - Reset data is added for am4/omap5 SoCs. - Some other minor tweaks. This series depends on the clock driver changes [1] due to patch #5, otherwise there will be build breakage. Also, just as a background note, this driver has been implemented under drivers/soc/ti due to the fact that I did not figure out any better home for it. In its current form it would be suitable to reside under drivers/reset, but there is a plan to extend this to support powerdomain handling also (PRM stands for Power and Reset Management.) -Tero [1] https://marc.info/?l=linux-clk&m=156697558331203&w=2 --- Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
