I haven't been able to follow or review the work on the driver for some
time now and I don't see the situation improving anytime soon. I'd like
to continue being listed as a reviewer.

When updating connector under drm_edid infrastructure, many calculations
and validations are already done and become redundant inside AMD driver.
Remove those driver-specific code in favor of the DRM common code.

extensive testing and validation of a large
variety of display caps and I don't have the required setup for it
(perhaps you can test it in your CI to point issues?). I don't see how
to reduce the scope of changes to mitigate the noise/disruption, but any

Enable usage of predefined transfer func in addition to shaper 1D LUT.
That means we can save some complexity by just setting a predefined
curve, instead of programming a custom curve when preparing color space
for applying 3D LUT.
