Richtek RT1711H TypeC PD Controller.

Required properties:
 - compatible : Must be "richtek,rt1711h".
 - reg : Must be 0x4e, it's slave address of RT1711H.
 - interrupts : <a b> where a is the interrupt number and b represents an
   encoding of the sense and level information for the interrupt.

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 :
rt1711h@4e {
	compatible = "richtek,rt1711h";
	reg = <0x4e>;
	interrupt-parent = <&gpio26>;
	interrupts = <0 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>;
				};
			};
		};
	};
};
