The first commit is needed for the second one to be reverted cleanly.

The second breaks DC support on my AMD 7750. Kernel panics and I get a
black screen on boot. With these two reverted, 6.12 is usable again.

Tried to git cherry-pick the fixes but that proved to be difficult to
do cleanly.

I see 6.6 also has these two commits.

Not sure what the proper procedure is to request reverts on stable
kernels.

  Revert "drm/amd/pm: Disable SCLK switching on Oland with high pixel
    clocks (v3)"

OK. I'll wait a bit before resubmitting.
