Thanks for sending this.  I should have been more clear.

Once you pull the current next tag from linux-next, take a look at the
SBC dtsi.  Specifically this excerpt from the file:

	usb@78d9000 {
		extcon = <&usb_id>;
		status = "okay";
		adp-disable;
		hnp-disable;
		srp-disable;
		dr_mode = "host";
		pinctrl-names = "default";
		pinctrl-0 = <&usb_sw_sel_pm>;
		ulpi {
			phy {
				v1p8-supply = <&pm8916_l7>;
				v3p3-supply = <&pm8916_l13>;
				extcon = <&usb_id>;
			};
		};
	};

	usb2513 {
		compatible = "smsc,usb3503";
		reset-gpios = <&pm8916_gpios 3 GPIO_ACTIVE_LOW>;
		initial-mode = <1>;
	};

	usb_id: usb-id {
		compatible = "linux,extcon-usb-gpio";
		vbus-gpio = <&msmgpio 121 GPIO_ACTIVE_HIGH>;
		pinctrl-names = "default";
		pinctrl-0 = <&usb_id_default>;

Looking at the Dart, you are using a USB2514, but it should be similar.
