Pull drm fixes from Dave Airlie:
 "Fixes for this week, bit larger than normal, but I think the last
  couple have been quieter, and it's only rc4.

  There are a lot of small msm fixes, and a slightly larger set of vc4
  fixes. The vc4 fixes clean up a lot of crashes around the rPI4
  hardware differences from earlier ones, and problems in the page flip
  and modeset code which assumed earlier hw, so I thought it would be
  okay to keep them in.

  Otherwise, it's a few amdgpu, i915, sun4i and a panel quirk.

  amdgpu:
   - Adjust GTT size logic
   - eDP fix for RMB
   - DCN 3.15 fix
   - DP training fix
   - Color encoding fix for DCN2+

  sun4i:
   - multiple suspend fixes

  vc4:
   - rework driver split for rpi4, fixes mulitple crashers.

  panel:
   - quirk for Aya Neo Next

  i915:
   - Revert low voltage SKU check removal to fix display issues
   - Apply PLL DCO fraction workaround for ADL-S
   - Don't show engine classes not present in client fdinfo

  msm:
   - Workaround for parade DSI bridge power sequencing
   - Fix for multi-planar YUV format offsets
   - Limiting WB modes to max sspp linewidth
   - Fixing the supported rotations to add 180 back for IGT
   - Fix to handle pm_runtime_get_sync() errors to avoid unclocked
     access in the bind() path for dpu driver
   - Fix the irq_free() without request issue which was a being hit
     frequently in CI.
   - Fix to add minimum ICC vote in the msm_mdss pm_resume path to
     address bootup splats
   - Fix to avoid dereferencing without checking in WB encoder
   - Fix to avoid crash during suspend in DP driver by ensuring
     interrupt mask bits are updated
   - Remove unused code from dpu_encoder_virt_atomic_check()
   - Fix to remove redundant init of dsc variable
   - Fix to ensure mmap offset is initialized to avoid memory corruption
     from unpin/evict
   - Fix double runpm disable in probe-defer path
   - VMA fenced-unpin fixes
   - Fix for WB max-width
   - Fix for rare dp resolution change issue"
