++MT8173 xHCI
++
++The device node for Mediatek SOC USB3.0 host controller
++
++Required properties:
++ - compatible : should contain "mediatek,mt8173-xhci"
++ - reg : specifies physical base address and size of the registers,
++ the first one for MAC, the second for IPPC
++ - interrupts : interrupt used by the controller
++ - power-domains : a phandle to USB power domain node to control USB's
++ mtcmos
++ - vusb33-supply : regulator of USB avdd3.3v
++
++ - clocks : a list of phandle + clock-specifier pairs, one for each
++ entry in clock-names
++ - clock-names : must contain
++ "sys_ck": for clock of xHCI MAC
++ "wakeup_deb_p0": for USB wakeup debounce clock of port0
++ "wakeup_deb_p0": for USB wakeup debounce clock of port1
++
++ - phys : a list of phandle + phy specifier pairs
++
++Optional properties:
++ - mediatek,wakeup-src : 1: ip sleep wakeup mode; 2: line state wakeup
++ mode;
++ - mediatek,syscon-wakeup : phandle to syscon used to access USB wakeup
++ control register, it depends on "mediatek,wakeup-src".
++ - vbus-supply : reference to the VBUS regulator;
++ - usb3-lpm-capable : supports USB3.0 LPM
++
++Example:
++usb30: usb@11270000 {
++ compatible = "mediatek,mt8173-xhci";
++ reg = <0 0x11270000 0 0x1000>,
++ <0 0x11280700 0 0x0100>;
++ interrupts = <GIC_SPI 115 IRQ_TYPE_LEVEL_LOW>;
++ power-domains = <&scpsys MT8173_POWER_DOMAIN_USB>;
++ clocks = <&topckgen CLK_TOP_USB30_SEL>,
++ <&pericfg CLK_PERI_USB0>,
++ <&pericfg CLK_PERI_USB1>;
++ clock-names = "sys_ck",
++ "wakeup_deb_p0",
++ "wakeup_deb_p1";
++ phys = <&phy_port0 PHY_TYPE_USB3>,
++ <&phy_port1 PHY_TYPE_USB2>;
++ vusb33-supply = <&mt6397_vusb_reg>;
++ vbus-supply = <&usb_p1_vbus>;
++ usb3-lpm-capable;
++ mediatek,syscon-wakeup = <&pericfg>;
++ mediatek,wakeup-src = <1>;
++};
