This is not really a backport candidate:
- This is not a fix, but a new feature.
- This relies on the H616 USB PHY support patch, which will be only in
  v6.2 (and won't be backported).
- DT backports are generally not useful to begin with, and should
  actually not be necessary anyway.

Cheers,
Andre
