Merge branch 'drm-next-4.17' of git://people.freedesktop.org/~agd5f/linux into drm-next
More stuff for 4.17. Highlights: - More fixes for "wattman" like functionality (fine grained clk/voltage control) - Add more power profile infrastucture (context based dpm) - SR-IOV fixes - Add iomem debugging interface for use with umr - Powerplay and cgs cleanups - DC fixes and cleanups - ttm improvements - Misc cleanups all over * 'drm-next-4.17' of git://people.freedesktop.org/~agd5f/linux: (143 commits) drm/amdgpu:Always save uvd vcpu_bo in VM Mode drm/amdgpu:Correct max uvd handles drm/amdgpu: replace iova debugfs file with iomem (v3) drm/amd/display: validate plane format on primary plane drm/amdgpu: Clean sdma wptr register when only enable wptr polling drm/amd/amdgpu: re-add missing GC 9.1 and SDMA0 4.1 sh_mask header files drm/amdgpu: give warning before sleep in kiq_r/wreg drm/amdgpu: further mitigate workaround for i915 drm/amdgpu: drop gtt->adev drm/amdgpu: add amdgpu_evict_gtt debugfs entry drm/amd/pp: Add #ifdef checks for CONFIG_ACPI drm/amd/pp: fix "Delete the wrapper layer of smu_allocate/free_memory" drm/amd/pp: Drop wrapper functions for upper/lower_32_bits drm/amdgpu: Delete cgs wrapper functions for gpu memory manager drm/amd/pp: Delete the wrapper layer of smu_allocate/free_memory drm/amd/pp: Remove cgs wrapper function for temperature update Revert "drm/amd/pp: Add a pp feature mask bit for AutoWattman feature" drm/amd/pp: Add auto power profilng switch based on workloads (v2) drm/amd/pp: Revert gfx/compute profile switch sysfs drm/amd/pp: Fix sclk in highest two levels when compute on smu7 ...
