Merge tag 'drm-fixes-2020-11-13' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Nearly didn't send you a PR this week at all, but a few things
  trickled in over the day, not a huge amount here, some i915, amdgpu
  and a bunch of misc fixes. I have a couple of nouveau fixes
  outstanding due to the PR having the wrong base, I'll figure it out
  next week.

  amdgpu:
   - Pageflip fix for DCN3
   - Declare TA firmware for green sardine
   - Headless navi fix

  i915:
   - Pull phys pread/pwrite implementations to the backend
   - Correctly set SFC capability for video engines

  bridge:
   - cdns Kconfig fix

  hyperv_fb:
   - fix missing include

  gma500:
   - oob access fix

  mcde:
   - unbalanced regulator fix"
