Hi Dave,
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
The following changes since commit 5c6c201ccbaf9d3901f829441d457293f7ca8ef4:
