Merge branch 'drm-next-5.2' of git://people.freedesktop.org/~agd5f/linux into drm-next

- Add the amdgpu specific bits for timeline support
- Add internal interfaces for xgmi pstate support
- DC Z ordering fixes for planes
- Add support for NV12 planes in DC
- Add colorspace properties for planes in DC
- eDP optimizations if the GOP driver already initialized eDP
- DC bandwidth validation tracing support
