Pull drm updates from Dave Airlie:
"Lots of stuff all over, some new AMD IP support and gang submit
support. i915 has further DG2 and Meteorlake pieces, and a bunch of
i915 display refactoring. msm has a shrinker rework. There are also a
bunch of conversions to use kunit.
This has two external pieces, some MEI changes needed for future Intel
discrete GPUs. These should be acked by Greg. There is also a cross
maintainer shared tree with some backlight rework from Hans in here.
Core:
- convert selftests to kunit
- managed init for more objects
- move to idr_init_base
- rename fb and gem cma helpers to dma
- hide unregistered connectors from getconnector ioctl
- DSC passthrough aux support
- backlight handling improvements
- add dma_resv_assert_held to vmap/vunmap
edid:
- move luminance calculation to core
fbdev:
- fix aperture helper usage
fourcc:
- add more format helpers
- add DRM_FORMAT_Cxx, DRM_FORMAT_Rxx, DRM_FORMAT_Dxx
- add packed AYUV8888, XYUV8888
- add some kunit tests
ttm:
- allow bos without backing store
- rewrite placement to use intersect/compatible functions
dma-buf:
- docs update
- improve signalling when debugging
udmabuf:

dp:
- drop dp/mst legacy code
- atomic mst state support
- audio infoframe packing
panel:
- Samsung LTL101AL01
- B120XAN01.0
- R140NWF5 RH
- DMT028VGHMCMI-1A T
- AUO B133UAN02.1
- IVO M133NW4J-R3
- Innolux N120ACA-EA1
amdgpu:
- Gang submit support
- Mode2 reset for RDNA2
- New IP support:
DCN 3.1.4, 3.2
SMU 13.x
NBIO 7.7
GC 11.x
PSP 13.x
SDMA 6.x
GMC 11.x
- DSC passthrough support
- PSP fixes for TA support
- vangogh GFXOFF stats
- clang fixes
- gang submit CS cleanup prep work
- fix VRAM eviction issues
amdkfd:
- GC 10.3 IP ISA fixes
- fix CRIU regression
- CPU fault on COW mapping fixes
i915:
- align fw versioning with kernel practices
- add display substruct to i915 private
- add initial runtime info to driver info
- split out HDCP and backlight registers
- MEI XeHP SDV GSC support
- add per-gt sysfs defaults
- TLB invalidation improvements
- Disable PCI BAR resize on 32-bit
- GuC firmware updates and compat changes

- misc dt-bindings fixes
- choose eDP as primary display if it's available
- support getting interconnects from either the mdss or the mdp5/dpu
device nodes
- gem: Shrinker + LRU re-work:
- adds a shared GEM LRU+shrinker helper and moves msm over to that
- reduce lock contention between retire and submit by avoiding the
need to acquire obj lock in retire path (and instead using resv
seeing obj's busyness in the shrinker
