+MediaTek musb DRD/OTG controller
+-------------------------------------------
+
+Required properties:
+ - compatible : should be "mediatek,mtk-musb"
+ - reg : specifies physical base address and size of
+ the registers
+ - interrupts : interrupt used by musb controller
+ - interrupt-names : must be "mc"
+ - phys : PHY specifier for the OTG phy
+ - dr_mode : should be one of "host", "peripheral" or "otg",
+ refer to usb/generic.txt
+ - clocks : a list of phandle + clock-specifier pairs, one for
+ each entry in clock-names
+ - clock-names : must contain "main", "mcu", "univpll"
+ for clocks of controller
+
+Optional properties:
+ - extcon : external connector for VBUS and IDPIN changes detection,
+ needed when supports dual-role mode.
+ - vbus-supply : reference to the VBUS regulator, needed when supports
+ dual-role mode.
+ - power-domains : a phandle to USB power domain node to control USB's
+ MTCMOS
+
+Example:
+
+usb2: usb@11200000 {
+ compatible = "mediatek,mt2701-musb",
+ "mediatek,mtk-musb";
+ reg = <0 0x11200000 0 0x1000>;
+ interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-names = "mc";
+ phys = <&u2port2 PHY_TYPE_USB2>;
+ vbus-supply = <&usb_vbus>;
+ extcon = <&extcon_usb>;
+ dr_mode = "otg";
+ clocks = <&pericfg CLK_PERI_USB0>,
+ <&pericfg CLK_PERI_USB0_MCU>,
+ <&pericfg CLK_PERI_USB_SLV>;
+ clock-names = "main","mcu","univpll";
+ power-domains = <&scpsys MT2701_POWER_DOMAIN_IFR_MSC>;
+};
