Merge tag 'drm-next-2022-03-25' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie:
"Some fixes were queued up in and in light of the fbdev regressions,
I've pulled those in as well.
core:
- Make audio and color plane support checking only happen when a CEA
extension block is found.
- Small selftest fix.
fbdev:
- two regressions fixes from speedup patches.
ttm:
- Fix a small regression from ttm_resource_fini()
i915:
- Reject unsupported TMDS rates on ICL+
- Treat SAGV block time 0 as SAGV disabled
- Fix PSF GV point mask when SAGV is not possible
- Fix renamed INTEL_INFO->media.arch/ver field"
