[SRU] [J] [PATCH 0/1] Fix PSR flickers on Intel TGL laptops + AUO panel

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1980087

[Impact]
Screen flickers on certain Intel TGL laptops + AUO panel.

[Fix]
Enable PSR2 selective fetch only for the specific case to minimize the
regression risk.

Previously an upstream version of PSR fix was pulled, but it caused an
regressoin on ADL + BOE panel [1]. So use a more cautious approach here.

[Test]
Screen flickers can no longer be observed on affected laptops.

[Where problems could occur]
The fix becomes very specific, so any other combination won't be affected at
all.
