In case of USB Type-C, those connector (port) nodes are child nodes of the controller or PHY device, in our case the fusb302. The software fwnodes allow us to create a similar child node for fusb302 that represents the connector also on Intel CHT. This makes it possible replace the fusb302 specific device properties which were deprecated with the common USB connector properties that tcpm.c is able to use directly.
