[PATCH 1/3] dt-bindings: extcon-usb-gpio: convert to DT schema format

[Alexander Stein <alexander.stein@ew.tq-group.com>]

Convert the binding to DT schema format. Change the GPIO properties to new
naming convention using -gpios as well.

-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"
-
-Either one of id-gpio or vbus-gpio must be present. Both can be present as well.
-- id-gpio: gpio for USB ID pin. See gpio binding.
-- vbus-gpio: gpio for USB VBUS pin.
-
-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>;
-	};
