[PATCH V9 0/3] powernv : Add support for OPAL-OCC command/response interface

[Shilpasri G Bhat]

In P9, OCC (On-Chip-Controller) supports shared memory based
commad-response interface. Within the shared memory there is an OPAL
command buffer and OCC response buffer that can be used to send
inband commands to OCC. The following commands are supported:

1) Set system powercap
2) Set CPU-GPU power shifting ratio
3) Clear min/max for OCC sensor groups

Changes from V9:
- Fixed return after erroring from mutex_lock_interruptible()
- Added documentation

Shilpasri G Bhat (3):
  powernv: powercap: Add support for powercap framework
  powernv: Add support to set power-shifting-ratio
  powernv: Add support to clear sensor groups data
