Merge branch 'drm-next-4.9' of git://people.freedesktop.org/~agd5f/linux into drm-next
First drm-next pull for radeon and amdgpu for 4.9. Highlights: - powerplay support for iceland asics - improved GPU reset (both full asic and per block) - UVD and VCE powergating for CZ and ST - VCE clockgating for CZ and ST - Support for pre-initialized (e.g., zeroed) vram buffers - ttm cleanups - virtual display support - core and radeon/amdgpu support for page_flip_target - lots of bug fixes and clean ups * 'drm-next-4.9' of git://people.freedesktop.org/~agd5f/linux: (171 commits) drm/amdgpu: use memcpy_toio for VCE firmware upload drm/amdgpu: use memcpy_to/fromio for UVD fw upload drm/amd/powerplay: delete useless code in iceland_hwmgr.c. drm/radeon: switch UVD code to use UVD_NO_OP for padding drm/amdgpu: switch UVD code to use UVD_NO_OP for padding drm/radeon: add support for UVD_NO_OP register drm/amdgpu: add support for UVD_NO_OP register drm/amdgpu: fix VCE ib alignment value drm/amdgpu: fix IB alignment for UVD drm/amd/amdgpu: Print ring name in amdgpu_ib_schedule() drm/radeon: remove dead code, si_mc_load_microcode (v2) drm/radeon/cik: remove dead code (v2) drm/amd/powerplay: avoid NULL dereference, cz_hwmgr.c drm/amd/powerplay: avoid NULL pointer dereference drm/amdgpu/gmc8: remove dead code (v2) drm/amdgpu/gmc7: remove dead code (v2) drm/amdgpu: Fix indentation in dce_v8_0_audio_write_sad_regs() drm/amdgpu: Use correct mask in dce_v8_0_afmt_setmode() and fix comment typos. drm/amdgpu: cleanup amdgpu_vm_bo_update params drm/amdgpu: stop adding dummy entry in amdgpu_ttm_placement_init ...
