1USB GPIO Extcon device 2 3This is a virtual device used to generate USB cable states from the USB ID pin 4connected to a GPIO pin. 5 6Required properties: 7- compatible: Should be "linux,extcon-usb-gpio" 8 9Either 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. 12 13Example: Examples of extcon-usb-gpio node in dra7-evm.dts as listed below: 14 extcon_usb1 { 15 compatible = "linux,extcon-usb-gpio"; 16 id-gpio = <&gpio6 1 GPIO_ACTIVE_HIGH>; 17 } 18 19 &omap_dwc3_1 { 20 extcon = <&extcon_usb1>; 21 };
