+TI HD3SS3220 TypeC DRP Port Controller.
+
+Required properties:
+ - compatible: Must be "ti,hd3ss3220".
+ - reg: I2C slave address, must be 0x47 or 0x67 based on ADDR pin.
+ - 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 hd3ss3220 chip. The
+ bindings of the connector node are specified in:
+
+ Documentation/devicetree/bindings/connector/usb-connector.txt
+
+Example:
+hd3ss3220@47 {
+ compatible = "ti,hd3ss3220";
+ reg = <0x47>;
+ interrupt-parent = <&gpio6>;
+ interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
