++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;
++};
