Merge tag 'drm-next-2020-08-06' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie:
"New xilinx displayport driver, AMD support for two new GPUs (more
header files), i915 initial support for RocketLake and some work on
their DG1 (discrete chip).
The core also grew some lockdep annotations to try and constrain what
drivers do with dma-fences, and added some documentation on why the
idea of indefinite fences doesn't work.
The long list is below.
I do have some fixes trees outstanding, but I'll follow up with those
later.
core:
- add user def flag to cmd line modes
- dma_fence_wait added might_sleep
- dma-fence lockdep annotations
- indefinite fences are bad documentation

- more drm_ debug macro usage
- set/drop master api fixes
- fix for drm/mm hole size comparison
- drm/mm remove invalid entry optimization
- optimise drm/mm hole handling
- VRR debugfs added
- uncompressed AFBC modifier support
- multiple display id blocks in EDID
