Merge tag 'drm-next-msm-5.8-2020-06-08' of git://anongit.freedesktop.org/drm/drm

Pull drm msm updates from Dave Airlie:
 "This tree has been in next for a couple of weeks, but Rob missed an
  arm32 build issue, so I was awaiting the tree with a patch reverted.

   - new gpu support: a405, a640, a650

   - dpu: color processing support

   - mdp5: support for msm8x36 (the thing with a405)

   - some prep work for per-context pagetables (ie the part that does
     not depend on in-flight iommu patches)

   - last but not least, UABI update for submit ioctl to support syncobj
     (from Bas)"
