Merge tag 'drm-fixes-2022-06-24' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Fixes for this week, bit larger than normal, but I think the last
  couple have been quieter, and it's only rc4.

  There are a lot of small msm fixes, and a slightly larger set of vc4
  fixes. The vc4 fixes clean up a lot of crashes around the rPI4
  hardware differences from earlier ones, and problems in the page flip
  and modeset code which assumed earlier hw, so I thought it would be
  okay to keep them in.

  Otherwise, it's a few amdgpu, i915, sun4i and a panel quirk.

  amdgpu:
   - Adjust GTT size logic
   - eDP fix for RMB
   - DCN 3.15 fix
   - DP training fix
   - Color encoding fix for DCN2+

  sun4i:
   - multiple suspend fixes

     access in the bind() path for dpu driver
