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>; |
|
};
