    1 USB GPIO Extcon device
    2 
    3 This is a virtual device used to generate USB cable states from the USB ID pin
    4 connected to a GPIO pin.
    5 
    6 Required properties:
    7 - compatible: Should be "linux,extcon-usb-gpio"
    8 
    9 Either one of id-gpio or vbus-gpio must be present. Both can be present as well.
   10 - id-gpio: gpio for USB ID pin. See gpio binding.
   11 - vbus-gpio: gpio for USB VBUS pin.
   12 
   13 Example: Examples of extcon-usb-gpio node in dra7-evm.dts as listed below:
   14         extcon_usb1 {
   15                 compatible = "linux,extcon-usb-gpio";
   16                 id-gpio = <&gpio6 1 GPIO_ACTIVE_HIGH>;
   17         }
   18 
   19         &omap_dwc3_1 {
   20                 extcon = <&extcon_usb1>;
   21         };
