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.
