-MediaTek musb DRD/OTG controller
--------------------------------------------
-
-Required properties:
- - compatible      : should be one of:
-                     "mediatek,mt2701-musb"
-                     ...
-                     followed by "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:
- - power-domains   : a phandle to USB power domain node to control USB's
-                     MTCMOS
-
-Required child nodes:
- usb connector node as defined in bindings/connector/usb-connector.yaml
-Optional properties:
- - id-gpios        : input GPIO for USB ID pin.
- - vbus-gpios      : input GPIO for USB VBUS pin.
- - vbus-supply     : reference to the VBUS regulator, needed when supports
-                     dual-role mode
- - usb-role-switch : use USB Role Switch to support dual-role switch, see
-                     usb/generic.txt.
-
-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>;
-	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>;
-	usb-role-switch;
-	connector{
-		compatible = "gpio-usb-b-connector", "usb-b-connector";
-		type = "micro";
-		id-gpios = <&pio 44 GPIO_ACTIVE_HIGH>;
-		vbus-supply = <&usb_vbus>;
