By setting up the DT graph from the USB-C connector for the SuperSpeed and SBU lanes to the PHY all mux/orientation operations are applied twice. I did not add any Fixes tag, since applying the settings twice is not breaking anything. But it's confusing when debugging USB-C issues and obviously wastes some CPU cycles.
