| 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. |
