According to the connector/usb-connector.txt, should the connector node
have ports, port@1 and an endpoint nodes like below?

	usb_con: connector {
		compatible = "usb-c-connector";
		label = "USB-C";
		data-role = "dual";

		ports {
			#address-cells = <1>;
			#size-cells = <0>;

			port@1 {
				reg = <1>;
				hd3ss3220_ep: endpoint {
					remote-endpoint = <&usb3peri_role_switch>;
				};
			};
		};
	};

Best regards,
Yoshihiro Shimoda
