description: |
  PTN5150 is a small thin low power CC logic chip supporting the USB Type-C
  connector application with CC control logic detection and indication
  functions.  It is interfaced to the host controller using an I2C interface.

properties:
  compatible:
    const: nxp,ptn5150

  int-gpios:
    maxItems: 1
    deprecated: true
    description:
      GPIO pin (input) connected to the PTN5150's INTB pin.
      Use "interrupts" instead.

  interrupts:
    maxItems: 1

  reg:
    maxItems: 1

  vbus-gpios:
    maxItems: 1
    description:
      GPIO pin (output) used to control VBUS. If skipped, no such control
      takes place.

  port:
    $ref: /schemas/graph.yaml#/properties/port
    description:
      A port node to link the usb controller for the dual role switch.
