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 = ; 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>; }; };
