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>;
|
};
