With performance state support for genpd merged, and with some more patches to add support for them in the OPP layer [1] under discussion, this is an effort to model a powerdomain driver to communicate corner/level values for qualcomm platforms to RPM (Remote Power Manager)
This series adds data specific to msm8996 and is tested on the db820c. We also modify mmc as one of the first devices to move to using an OPP table and vote on corners using the performance state infrastructure.
