+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>;
+		};
+	}
