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