+USB GPIO Based Connection Detection
+
+This is typically used to switch dual role mode from the USB ID pin connected
+to an input GPIO, and also used to enable/disable device mode from the USB
+Vbus pin connected to an input GPIO.
+
+Required properties:
+- compatible : should include "gpio-usb-b-connector" and "usb-b-connector".
+- id-gpios, vbus-gpios : input gpios, either one of them must be present,
+	and both can be present as well.
+	see connector/usb-connector.txt
+
+Optional properties:
+- vbus-supply : can be present if needed when supports dual role mode.
+	see connector/usb-connector.txt
+
+- Sub-nodes:
+	- port : can be present.
+		see graph.txt
+
+Example:
+
+&mtu3 {
+	connector {
+		compatible = "gpio-usb-b-connector", "usb-b-connector";
+		type = "micro";
+		id-gpios = <&pio 12 GPIO_ACTIVE_HIGH>;
+		vbus-supply = <&usb_p0_vbus>;
+	};
+};
