As I believe someone already pointed out, this node is not in sort order
(i.e. it should go before usb@a6f8800).

This is not the correct interconnect master and slave; it should be
MASTER_USB3_MP and SLAVE_USB3_MP.

Looks like 'wakeup-source' is missing here too.

The phys and phy-names continuation lines above are still not aligned.
