[U-Boot] [PATCH 02/16] phy: usbphyc: update xlate with DT binding

[Patrick Delaunay]

Parameter added for port 1, for example:

&usbh_ehci {
        phys = <&usbphyc_port0>;
        phy-names = "usb";
        vbus-supply = <&vbus_sw>;
        status = "okay";
};

&usbotg_hs {
        pinctrl-names = "default";
        pinctrl-0 = <&usbotg_hs_pins_a>;
        phys = <&usbphyc_port1 0>;
        phy-names = "usb2-phy";
        status = "okay";
};
