Merge branch 'drm-next-4.9' of git://people.freedesktop.org/~agd5f/linux into drm-next

Browse source 
Last set of radeon and amdgpu changes for 4.9.  This is
mostly just the powerplay cleanup for dGPUs.  Beyond that,
just misc code cleanups and bug fixes.

* 'drm-next-4.9' of git://people.freedesktop.org/~agd5f/linux: (49 commits)
  drm/amd/amdgpu: Clean up afmt allocation in DCEv6. (v2)
  drm/amd/amdgpu: Remove division from vblank_wait
  drm/radeon/atif: Send a hotplug event when we get dgpu display request
  drm/radeon/atpx: check for ATIF dGPU wake for display events support
  drm/amdgpu/atif: Send a hotplug event when we get dgpu display request
  drm/amdgpu/atpx: check for ATIF dGPU wake for display events support
  drm/amdgpu: bump version for new vce packet support
  drm/amdgpu/vce: allow the clock table packet
  drm/amdgpu:cleanup virt related define
  drm/amdgpu: use powerplay module for dgpu in Vi.
  drm/amdgpu: set gfx clock gating for tonga/polaris.
  drm/amdgpu: set system clock gating for tonga/polaris.
  drm/amd/powerplay: export function to help to set cg by smu.
  drm/amdgpu: avoid out of bounds access on array interrupt_status_offsets
  drm/amdgpu: mark symbols static where possible
  drm/amdgpu: remove unused functions
  drm/amd/powerplay:  Replace per-asic print_performance with generic
  drm/radeon: narrow asic_init for virtualization
  drm/amdgpu:add fw version entry to info
  drm/amdgpu:determine if vPost is needed indeed
