   2 ---------------------------------------------
   3
   4 Required properties:
   5 - compatible:       should be set one of following:
   6                     - "nxp,ptn5110" for NXP USB PD TCPC PHY IC ptn5110.
   7
   8 - reg:              the i2c slave address of typec port controller device.
   9 - interrupt-parent: the phandle to the interrupt controller which provides
  10                     the interrupt.
  11 - interrupts:       interrupt specification for tcpci alert.
  12
  13 Required sub-node:
  14 - connector: The "usb-c-connector" attached to the tcpci chip, the bindings
  15   of connector node are specified in
  16   Documentation/devicetree/bindings/connector/usb-connector.yaml
