description:
  The FSA880 and FSA9480 are USB port accessory detectors and switches.
  The switch is fully controlled using I2C and enables USB data, stereo
  and mono audio, video, microphone, and UART data to use a common
  connector port. Compatible switches exist from other manufacturers.

properties:
  compatible:
    enum:
      - fcs,fsa880
      - fcs,fsa9480
      - ti,tsu6111

  reg:
    maxItems: 1
    description: The I2C address for an FSA880 compatible device is
      usually 0x25.

  interrupts:
    maxItems: 1

required:
  - compatible
  - reg
  - interrupts

additionalProperties: false
