These capabilities enable the PHY itself to handle both mode switching and orientation switching, based on the Type-C plug orientation and USB PD negotiation results. While an external Type-C controller is still required to detect cable attachment and report USB PD events, the actual mode and orientation switching is performed internally by the PHY through software configuration. This allows the PHY to act as a Type-C multiplexer for both data role and DP altmode configuration. To reflect this hardware design, this patch introduces a new "mode-switch" property for the dp-port node in the device tree bindings. This property indicates that the connected PHY is capable of handling Type-C mode switching itself.
