Merge tag 'drm-fixes-2024-01-04' of git://anongit.freedesktop.org/drm/drm 

Pull drm fixes from Dave Airlie:
 "These were from over the holiday period, mainly i915, a couple of
  qaic, bridge and an mgag200.

  qaic:
   - fix GEM import
   - add quirk for soc version

  bridge:
   - parade-ps8640, ti-sn65dsi86: fix aux reads bounds

  mgag200:
   - fix gamma LUT init

  i915:
   - Fix bogus DPCD rev usage for DP phy test pattern setup
   - Fix handling of MMIO triggered reports in the OA buffer"
