amd-drm-next-5.7-2020-03-10:

amdgpu:
- SR-IOV fixes
- Fix up fallout from drm load/unload callback removal
- Navi, renoir power management watermark fixes
- Refactor smu parameter handling
- Display FEC fixes
- Display DCC fixes
- HDCP fixes
- Add support for USB-C PD firmware updates
- Pollock detection fix
- Rework compute ring priority handling
- RAS fixes
- Misc cleanups

amdkfd:
- Consolidate more gfx config details in amdgpu
- Consolidate bo alloc flags
- Improve code comments
- SDMA MQD fixes
- Misc cleanups

gpu scheduler:
- Add suport for modifying the sched list

uapi:
- Clarify comments about GEM_CREATE flags that are not used by userspace.
  The kernel driver has always prevented userspace from using these.
  They are only used internally in the kernel driver.
