EXTCON FOR USB VIA GPIO

Required Properties:
 - compatible : Should be "ti,gpio-usb-vid" for USB VBUS-ID detector
		using gpios or "ti,gpio-usb-id" for USB ID pin detector
 - gpios : phandle and args ID pin gpio and VBUS gpio.
	   The first gpio used  for ID pin detection
	   and the second used for VBUS detection.
	   ID pin gpio is mandatory and VBUS is optional
	   depending on implementation.

Please refer to ../gpio/gpio.txt for details of the common GPIO bindings

Example:

	gpio_usbvid_extcon1 {
		compatible = "ti,gpio-usb-vid";
		gpios = <&gpio1 1 0>,
			<&gpio2 2 0>;
	};
