Is it possible to cherry-pick these 2 patches to stable branches?
These 2 patches help fix USB port 1 (xhci1) for board mt8395-genio-1200-evb.
The following branch has been tested.
  - linux-6.7.y (6.7.5): apply test, build pass, function tested OK 
(with corresponded dtb change).
  - linux-6.6.y (6.6.17): apply test, build pass.
  - linux-6.1.y (6.1.78): apply test, build pass.

Thanks.
