The Lenovo ThinkBook 16p Gen4 IRH seems has no correct quirk for the AMP.

Wondering if there are any support from Lenvovo or Cirrus, because the community has nothing to do with the TRUE bits for the QUIRK.

Thanks a lot.

Same goes for Lenovo Slim 7 16" AMD, 16ARH7, 82UX0001US. (And this same model is called Yoga outside the United States.)

The brightness keys also do not work on the Slim it seems.

I can also provide any outputs from dmesg, journalctl, etc if any would be helpful.

Thanks!
