Subject: [PATCH 0/7] Add powerdomain driver for corners on msm8996

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.
