+USB GPIO Extcon device
+
+This is a virtual device used to generate USB cable states from the USB ID pin
+connected to a GPIO pin.
+
+Required properties:
+- compatible: Should be "linux,extcon-usb-gpio"
+- id-gpio: gpio for USB ID pin. See gpio binding.
+
+Example: Examples of extcon-usb-gpio node in dra7-evm.dts as listed below:
+        extcon_usb1 {
+                compatible = "linux,extcon-usb-gpio";
+                id-gpio = <&gpio6 1 GPIO_ACTIVE_HIGH>;
+        }
+
+        &omap_dwc3_1 {
+                extcon = <&extcon_usb1>;
+        };
