TCPCI(Typec port cotroller interface) binding
---------------------------------------------

Required properties:
- compatible:       should be set one of following:
		    - "nxp,ptn5110" for NXP USB PD TCPC PHY IC ptn5110.

- reg:              the i2c slave address of typec port controller device.
- interrupt-parent: the phandle to the interrupt controller which provides
                    the interrupt.
- interrupts:       interrupt specification for tcpci alert.

Required sub-node:
- connector: The "usb-c-connector" attached to the tcpci chip, the bindings
  of connector node are specified in
  Documentation/devicetree/bindings/connector/usb-connector.txt

Example:

ptn5110@50 {
	compatible = "nxp,ptn5110";
	reg = <0x50>;
	interrupt-parent = <&gpio3>;
	interrupts = <3 IRQ_TYPE_LEVEL_LOW>;

	usb_con: connector {
		compatible = "usb-c-connector";
		label = "USB-C";
		data-role = "dual";
		power-role = "dual";
		try-power-role = "sink";
		source-pdos = <PDO_FIXED(5000, 2000, PDO_FIXED_USB_COMM)>;
		sink-pdos = <PDO_FIXED(5000, 2000, PDO_FIXED_USB_COMM)
			     PDO_VAR(5000, 12000, 2000)>;
		op-sink-microwatt = <10000000>;

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

			port@1 {
				reg = <1>;
				usb_con_ss: endpoint {
					remote-endpoint = <&usb3_data_ss>;
				};
			};
		};
	};
};
