| 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>; |
| }; |
