The subject is misleading, this patch doesn't add the binding for the USB3 DP
PHY, but factors it out.

Probably not a new problem, but where are the child node properties
documented? They need to be added before you duplicate this problem.

You're missing 'ranges', so the child addresses are not translatable.

You could also reduce everything to 1 cell as they are contained within
the parent's range.
