drm/amd/powerplay: Replace per-asic print_performance with generic

2016-09-22T14:24:16+00:00

Replace per-asic print_current_performance() functions with generic
that calls read_sensor.  Tested on Tonga and Carrizo for aesthetics
and accuracy.

drm/amd/amdgpu: add mutex locking for both DPM and PP based powergating for UVD/VCE

2016-08-08T15:32:36+00:00

This adds a mutex lock for both DPM/PP around the changes in
power gating state so that userspace can poll registers without
a race condition on power state.

drm/amdgpu: missing bounds check in amdgpu_set_pp_force_state()

2016-06-17T17:50:10+00:00

There is no limit on high "idx" can go.  It should be less than
ARRAY_SIZE(data.states) which is 16.

The "data" variable wasn't declared in that scope so I shifted the code
around a bit to make it work.  Also I made "idx" unsigned.
