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"
