Pull drm fixes from Dave Airlie:
 "Regular fixes for final, there is a ttm regression fix, dp-mst fix,
  one amdgpu revert, two i915 fixes, and some misc fixes for sun4i,
  xlnx, and vc4.

  All pretty quiet and don't think we have any known outstanding
  regressions.

  ttm:
   - page pool regression fix.

  dp_mst:
   - don't report un-attached ports as connected

  amdgpu:
   - blank screen fix

  i915:
   - ensure Type-C FIA is powered when initializing
   - fix overlay frontbuffer tracking

  sun4i:
   - tcon1 sync polarity fix
   - always set HDMI clock rate
   - fix H6 HDMI PHY config
   - fix H6 max frequency

  vc4:
   - fix buffer overflow

  xlnx:
   - fix memory leak"
