Merge branch 'drm-fixes-4.6' of git://people.freedesktop.org/~agd5f/linux into drm-fixes

Lots of misc bug fixes for radeon and amdgpu and one for ttm.
- fix vram info fetching on Fiji and unposted boards
- additional vblank fixes from the conversion to drm_vblank_on/off
- UVD dGPU suspend and resume fixes
- lots of powerplay fixes
- fix a fence leak in the pageflip code
- ttm fix for platforms where CPU is 32 bit, but physical addresses are >32bits

* 'drm-fixes-4.6' of git://people.freedesktop.org/~agd5f/linux: (21 commits)
  drm/amdgpu: total vram size also reduces pin size
  drm/amd/powerplay: add uvd/vce dpm enabling flag default.
  drm/amd/powerplay: fix issue that resume back, dpm can't work on FIJI.
  drm/amdgpu: save and restore the firwmware cache part when suspend resume
  drm/amdgpu: save and restore UVD context with suspend and resume
  drm/ttm: use phys_addr_t for ttm_bus_placement
  drm/radeon: Only call drm_vblank_on/off between drm_vblank_init/cleanup
  drm/amdgpu: fence wait old rcu slot
  drm/amdgpu: fix leaking fence in the pageflip code
  drm/amdgpu: print vram type rather than just DDR
  drm/amdgpu/gmc: use proper register for vram type on Fiji
  drm/amdgpu/gmc: move vram type fetching into sw_init
  drm/amdgpu: Set vblank_disable_allowed = true
  drm/radeon: Set vblank_disable_allowed = true
  drm/amd/powerplay: Need to change boot to performance state in resume.
  drm/amd/powerplay: add new Fiji function for not setting same ps.
  drm/amdgpu: check dpm state before pm system fs initialized.
  drm/amd/powerplay: notify amdgpu whether dpm is enabled or not.
  drm/amdgpu: Not support disable dpm in powerplay.
  drm/amdgpu: add an cgs interface to notify amdgpu the dpm state.
