Merge tag 'drm-fixes-2021-03-26' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "As expected last week things were overly quiet so this week things
  seem to have caught up. It still isn't too major.

  msm and amdgpu lead the size here, the msm fixes are pretty varied
  across the driver, the amdgpu one is mostly the S0ix fixes with some
  other minor ones. Otherwise there are a few i915 fixes and one each
  for nouveau, etnaviv and rcar-du.

  msm:
   - pll fixes
   - shutdown hook fix
   - runtime resume fix
   - clear_oob fix
   - kms locking fix
   - display aux retry fix

  rcar-du:
   - warn_on in encoder init fix

  etnaviv:
   - Use FOLL_FORCE and FOLL_LONGTERM

  i915:
   - DisplayPort LTTPR fixes around link training and limiting it
     according to supported spec version.
   - Fix enabled_planes bitmask to really represent only logically
     enabled planes.
   - Fix DSS CTL registers for ICL DSI transcoders
   - Fix the GT fence revocation runtime PM logic.

  nouveau:
   - cursor size regression fix

  amdgpu:
   - S0ix fixes
   - Add PCI ID
   - Polaris PCIe DPM fix
   - Display fix for high refresh rate monitors"
