Add a ports declaration which is optional containing two port@ declarations. port@0 to receive an orientation-switch message from the Type-C port or redriver port@1 to subsequently transmit the orientation-switch on once the PHY has finished doing its orientation turn-around. If ports is declared the input port port@0 is mandatory but the output port@1 is optional.
