Merge tag 'drm-next-5.5-2019-10-09' of git://people.freedesktop.org/~agd5f/linux into drm-next 

drm-next-5.5-2019-10-09:

amdgpu:
- Additional RAS enablement for vega20
- RAS page retirement and bad page storage in EEPROM
- No GPU reset with unrecoverable RAS errors
- Reserve vram for page tables rather than trying to evict
- Fix issues with GPU reset and xgmi hives
- DC i2c over aux fixes
- Direct submission for clears, PTE/PDE updates
- Improvements to help support recoverable GPU page faults
- Silence harmless SAD block messages
- Clean up code for creating a bo at a fixed location
- Initial DC HDCP support
- Lots of documentation fixes
- GPU reset for renoir
- Add IH clockgating support for soc15 asics
- Powerplay improvements
- DC MST cleanups
- Add support for MSI-X
- Misc cleanups and bug fixes

amdkfd:
- Query KFD device info by asic type rather than pci ids
- Add navi14 support
- Add renoir support
- Add navi12 support
- gfx10 trap handler improvements
- pasid cleanups
- Check against device cgroup

ttm:
- Return -EBUSY with pipelining with no_gpu_wait

radeon:
- Silence harmless SAD block messages

device_cgroup:
- Export devcgroup_check_permission
