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.

+Consolidate custom driver modeset properties
+--------------------------------------------
+
+Before atomic modeset took place, many drivers where creating their own
+properties. Among other things, atomic brought the requirement that custom,
+driver specific properties should not be used.
+
+For this task, we aim to introduce core helpers or reuse the existing ones
+if available:
+
+A quick, unconfirmed, examples list.
+
+Introduce core helpers:
+- audio (amdgpu, intel, gma500, radeon)
+- brightness, contrast, etc (armada, nouveau) - overlay only (?)
+- broadcast rgb (gma500, intel)
+- colorkey (armada, nouveau, rcar) - overlay only (?)
+- dither (amdgpu, nouveau, radeon) - varies across drivers
+- underscan family (amdgpu, radeon, nouveau)
+
+Already in core:
+- colorspace (sti)
+- tv format names, enhancements (gma500, intel)
+- tv overscan, margins, etc. (gma500, intel)
+- zorder (omapdrm) - same as zpos (?)
