+-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.
