Merge branch 'drm-next-4.5' of git://people.freedesktop.org/~agd5f/linux into drm-next

Browse Source 
A few more misc things for radeon and amdgpu for 4.5:
- TTM fixes for imported buffers
- amdgpu fixes to avoid -ENOMEM in CS ioctl
- CZ UVD and VCE clock force options for debugging video issues
- A couple of ACP prerequisites
- Misc fixes

* 'drm-next-4.5' of git://people.freedesktop.org/~agd5f/linux:
  drm/amdgpu: validate duplicates first
  drm/amdgpu: move VM page tables to the LRU end on CS v2
  drm/ttm: add ttm_bo_move_to_lru_tail function v2
  drm/ttm: fix adding foreign BOs to the swap LRU
  drm/ttm: fix adding foreign BOs to the LRU during init v2
  drm/radeon: use kobj_to_dev()
  drm/amdgpu: use kobj_to_dev()
  drm/amdgpu/cz: force vce clocks when sclks are forced
  drm/amdgpu/cz: force uvd clocks when sclks are forced
  drm/amdgpu/cz: add code to enable forcing VCE clocks
  drm/amdgpu/cz: add code to enable forcing UVD clocks
  drm/amdgpu: fix lost sync_to if scheduler is enabled.
  drm/amd/powerplay: fix static checker warning for return meaningless value.
  drm/amdgpu: add irq domain support
  drm/amdgpu/cgs: add an interface to access PCI resources
