description:

  Chrome OS devices have an Embedded Controller(EC) which has access to

  Type C port state. This node is intended to allow the host to read and

  control the Type C ports. The node for this device should be under a

  cros-ec node like google,cros-ec-spi.

properties:

  compatible:

    const: google,cros-ec-typec
