amd-drm-next-5.13-2021-03-23:

amdgpu:
- Debugfs cleanup
- Various cleanups and spelling fixes
- Flexible array cleanups
- Initial AMD Freesync HDMI
- Display fixes
- 10bpc dithering improvements
- Display ASSR support
- Clean up and unify powerplay and swsmu interfaces
- Vangogh fixes
- Add SMU gfx busy queues for RV/PCO
- PCIE DPM fixes
- S0ix fixes
- GPU metrics data fixes
- DCN secure display support
- Backlight type override
- Add initial support for Aldebaran
- RAS fixes
- Prime fixes for A+A systems
- Reset fixes
- Initial resource cursor support
- Drop legacy IO BAR requirements
- Various power fixes

amdkfd:
- MMU notifier fixes
- APU fixes

radeon:
- Debugfs cleanups
- Flexible array cleanups

UAPI:
- amdgpu: Add a new INFO ioctl interface to query video capabilities
  rather than hardcoding them in userspace.  This allows us to provide
  fine grained asic capabilities (e.g., if a particular part is
  bandwidth limited, we can limit the capabilities).  Proposed userspace:
  https://gitlab.freedesktop.org/leoliu/drm/-/commits/info_video_caps
  https://gitlab.freedesktop.org/leoliu/mesa/-/commits/info_video_caps
- amdkfd: bump the driver version.  There was a problem with reporting
  some RAS features on older versions of the driver. Proposed userspace:
  7cdd63475c

Danvet: A bunch of conflicts all over, but it seems to compile ... I
did put the call to dc_allow_idle_optimizations() on a single line
since it looked a bit too jarring to be left alone.
