Revision f939a5f432981872f89d4dfe506e959f49cc161a authored by Dave Airlie on 24 June 2016, 00:51:12 UTC, committed by Dave Airlie on 24 June 2016, 00:51:12 UTC 
Merge branch 'drm-fixes-4.7' of git://people.freedesktop.org/~agd5f/linux into drm-fixes
 
A bit bigger than I would normally like, but most of the large changes are
for polaris support and since polaris went upstream in 4.7, I'd like
to get the fixes in so it's in good shape when the hw becomes available.
The major changes only touch the polaris code so there is little chance
for regressions on other asics.  The rest are just the usual collection
of bug fixes.

* 'drm-fixes-4.7' of git://people.freedesktop.org/~agd5f/linux:
  drm/amd/powerplay: enable clock stretch feature for polaris
  drm/amdgpu/gfx8: update golden setting for polaris10
  drm/amd/powerplay: enable avfs feature for polaris
  drm/amdgpu/atombios: add avfs struct for Polaris10/11
  drm/amd/powerplay: add avfs related define for polaris
  drm/amd/powrplay: enable stutter_mode for polaris.
  drm/amd/powerplay: disable UVD SMU handshake for MCLK.
  drm/amd/powerplay: initialize variables which were missed.
  drm/amd/powerplay: enable PowerContainment feature for polaris10/11.
  drm/amd/powerplay: need to notify system bios pcie device ready
  drm/amd/powerplay: fix bug that function parameter was incorect.
  drm/amd/powerplay: fix logic error.
  drm/amdgpu: initialize amdgpu_cgs_acpi_eval_object result value
  drm/amdgpu: precedence bug in amdgpu_device_init()
  drm/amdgpu: fix num_rbs exposed to userspace (v2)
  drm/amdgpu: missing bounds check in amdgpu_set_pp_force_state()
