[PATCH v2 0/6] Add powerdomain driver for corners on msm8996/sdm845

[Rajendra Nayak]

Changes in v2:
* added a powerdomain driver for sdm845 which supports communicating to RPMh
* dropped the changes to sdhc driver to move over to using OPP
as there is active discussion on using OPP as the interface vs
handling all of it in clock drivers
* Other minor binding updates based on review of v1

With performance state support for genpd merged, and with some more
patches to add support for them in the OPP layer [1] in linux-next,
this is an effort to model a powerdomain driver to communicate corner/level
values for qualcomm platforms to RPM (Remote Power Manager) and RPMh.

The series is based on linux-next as it depends on OPP updates and SMD845
specific patches which are all in linux-next. It also depends on the RPMH
communication patches [2] for the sdm845 rpmhpd driver.
