Pull drm updates from Dave Airlie:
 "There is a new Qualcomm accel driver for their QAIC, dma-fence got a
  deadline feature added, lots of refactoring around fbdev emulation,
  and the usual pre-release hw enablements from AMD and Intel and fixes
  everywhere.

  New drivers:

   - constify kobj_type structs
   - Reject prime DMA-Buf attachment if get_sg_table is missing.

  fbdev:
   - cmdline parser fixes
   - implement fbdev emulation for GEM DMA drivers
   - always use shadow buffer in fbdev emulation helpers

   - add deadline hint to fences
   - signal private stub fence

  core:
   - improve DisplayID 2.0 and EDID parsing
   - add gem eviction function + callback
   - prep to convert shmem helper to GEM resv lock
   - move suballocator from radeon/amdgpu to core for Xe
   - HPD polling fixes
   - Documentation improvements
   - Add atomic enable_plane callback

   - Fix GSC races on driver load/unload on Meteorlake+
   - Make kobj_type structures constant
   - Move fd_install after last use of fence
   - wm/vblank refactoring
   - display code refactoring
   - Create GSC submission targeting HDCP and PXP usages on MTL+
   - Enable HDCP2.x via GSC CS

     reserve for themselves.
   - INFO ioctl a bit-mask of the available rotator engines
