Merge tag 'drm-next-2025-01-17' of https://gitlab.freedesktop.org/drm/kernel

Pull drm updates from Dave Airlie:
 "There are two external interactions of note, the msm tree pull in some
  opp tree, hopefully the opp tree arrives from the same git tree
  however it normally does.

  There is also a new cgroup controller for device memory, that is used
  by drm, so is merging through my tree. This will hopefully help open
  up gpu cgroup usage a bit more and move us forward.

  There is a new accelerator driver for the AMD XDNA Ryzen AI NPUs.

  Then the usual xe/amdgpu/i915/msm leaders and lots of changes and
  refactors across the board:

   - SRIOV PF scheduling priority
   - allow fault injection
   - lots of improvements/refactors
   - Enable GuC's WA_DUAL_QUEUE for newer platforms
   - IRQ related fixes and improvements

  i915:
   - More accurate engine busyness metrics with GuC submission
   - Ensure partial BO segment offset never exceeds allowed max
   - Flush GuC CT receive tasklet during reset preparation

   - Fix DG1 power gate sequence
   - Enabling uncompressed 128b/132b UHBR SST
   - Handle hdmi connector init failures, and no HDMI/DP cases
   - More robust engine resets on Haswell and older

  i915/xe display:
