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

- add dma_resv_assert_held to vmap/vunmap
edid:
- move luminance calculation to core
fbdev:
- fix aperture helper usage
