+MT65xx U3PHY
+
+The device node for Mediatek SOC usb3.0 phy
+
+Required properties:
+ - compatible : Should be "mediatek,mt8173-u3phy"
+ - reg : Offset and length of registers, the first is for mac domain,
+ another for phy domain
+ - power-domains: to enable usb's mtcmos
+ - reg-vusb33-supply: regulator of usb avdd3.3v
+ - clocks : must support all clocks that phy need
+ - clock-names: should be "wakeup_deb_p0", "wakeup_deb_p1" for wakeup
+ debounce control clocks, "sys_mac" for sys and mac clocks and
+ "u3phya_ref" for u3phya reference clock.
+
+Optional properties:
+ - disable-usb2-p1 : disable port1 of usb2.0 which has two ports.
+ - reg-p1-vbus-supply : regulator of port1's vbus;
+
+Example:
+
+u3phy: usb-phy@11271000 {
+ compatible = "mediatek,mt8173-u3phy";
+ reg = <0 0x11271000 0 0x3000>,
+ <0 0x11280000 0 0x20000>;
+ power-domains = <&scpsys MT8173_POWER_DOMAIN_USB>;
+ reg-vusb33-supply = <&mt6397_usb_reg>;
+ clocks = <&perisys PERI_USB0>,
+ <&perisys PERI_USB1>,
+ <&topckgen CLK_TOP_USB30_SEL>,
+ <&apmixedsys CLK_APMIXED_REF2USB_TX>;
+ clock-names = "wakeup_deb_p0",
+ "wakeup_deb_p1",
+ "sys_mac",
+ "u3phya_ref";
+ disable-usb2-p1;
