FWIW, that's 3cf050762534 in mainline. Adding Ville, its author to the list of recipients.
I definitely had no plans to backport any of that stuff, but I guess the automagics did it anyway.
Looks like stable is at least missing this pile of stuff: 50759c13735d drm/i915/pps: Keep VDD enabled during eDP probe 67090801489d drm/i915/pps: Reinit PPS delays after VBT has been fully

But dunno if even that is enough.
If you need testers: David (now CCed) apparently has a affected machine and offered to test patches in a different subthread of this thread.
I cherry-picked the six commits Thorsten listed onto 5.19.12 and it resolved the issue on my Framework laptop.
Thanks for testing, but I'm just going to revert the offending commits as they probably shouldn't all be added to 5.19.y
thanks,

Yeah, revert seems the safer route. Thanks.

5.19.13 is now released with 8 reverts for this driver, hopefully that sould resolve this issue.
