Hi,

V2 of the series mostly has comments fixed from Suman.
- Added a link between reset + clock drivers to sync up the state between
  these; this is to avoid facing any timeout issues on either end due to
  sequencing of events (Patch #5.) 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.)
