ChromeOS EC USB Type-C cable and accessories detection
|
||||
|
||||
On ChromeOS systems with USB Type C ports, the ChromeOS Embedded Controller is
|
||||
able to detect the state of external accessories such as display adapters
|
||||
or USB devices when said accessories are attached or detached.
|
||||
|
||||
The node for this device must be under a cros-ec node like google,cros-ec-spi
|
||||
or google,cros-ec-i2c.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be "google,extcon-usbc-cros-ec".
|
||||
- google,usb-port-id: Specifies the USB port ID to use.
|
||||
|
||||
Example:
|
||||
cros-ec@0 {
|
||||
compatible = "google,cros-ec-i2c";
|
||||
|
||||
...
|
||||
|
||||
extcon {
|
||||
compatible = "google,extcon-usbc-cros-ec";
|
||||
google,usb-port-id = <0>;
|
||||
};
|
