+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
