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
