With support for the QMP combo phy to react to USB Type-C switch events, introduce it as the next hop for the SuperSpeed lanes of the Type-C connector, and connect the output of the DisplayPort controller to the QMP combo phy. This allows the TCPM to perform orientation switching of both USB and DisplayPort signals.
