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>; };
