3 This is a virtual device used to generate USB cable states from the USB ID pin
4 connected to a GPIO pin.
7 - compatible: Should be "linux,extcon-usb-gpio"
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.
13 Example: Examples of extcon-usb-gpio node in dra7-evm.dts as listed below:
15 compatible = "linux,extcon-usb-gpio";
16 id-gpio = <&gpio6 1 GPIO_ACTIVE_HIGH>;
20 extcon = <&extcon_usb1>;
