-The device node for Mediatek USB3.0 DRD controller
-
-Required properties:
- - compatible : should be "mediatek,-mtu3", "mediatek,mtu3",
- soc-model is the name of SoC, such as mt8173, mt2712 etc,
- when using "mediatek,mtu3" compatible string, you need SoC specific
- ones in addition, one of:
- - "mediatek,mt8173-mtu3"
- - reg : specifies physical base address and size of the registers
- - reg-names: should be "mac" for device IP and "ippc" for IP port control
- - interrupts : interrupt used by the device IP
- - power-domains : a phandle to USB power domain node to control USB's
- mtcmos
- - vusb33-supply : regulator of USB avdd3.3v
- - clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
- - clock-names : must contain "sys_ck" for clock of controller,
- the following clocks are optional:
- "ref_ck", "mcu_ck" and "dma_ck";
- - phys : see usb-hcd.yaml in the current directory
- - dr_mode : should be one of "host", "peripheral" or "otg",
- refer to usb/generic.txt
-
-Optional properties:
- - #address-cells, #size-cells : should be '2' if the device has sub-nodes
- with 'reg' property
- - ranges : allows valid 1:1 translation between child's address space and
- parent's address space
- - extcon : external connector for vbus and idpin changes detection, needed
- when supports dual-role mode.
- it's considered valid for compatibility reasons, not allowed for
- new bindings, and use "usb-role-switch" property instead.
- - vbus-supply : reference to the VBUS regulator, needed when supports
- dual-role mode.
- it's considered valid for compatibility reasons, not allowed for
- new bindings, and put into a usb-connector node.
- see connector/usb-connector.yaml.
- - pinctrl-names : a pinctrl state named "default" is optional, and need be
- defined if auto drd switch is enabled, that means the property dr_mode
- is set as "otg", and meanwhile the property "mediatek,enable-manual-drd"
- is not set.
- - pinctrl-0 : pin control group
- See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
-
- - maximum-speed : valid arguments are "super-speed", "high-speed" and
- "full-speed"; refer to usb/generic.txt
- - usb-role-switch : use USB Role Switch to support dual-role switch, but
- not extcon; see usb/generic.txt.
- - enable-manual-drd : supports manual dual-role switch via debugfs; usually
- used when receptacle is TYPE-A and also wants to support dual-role
- mode.
- - wakeup-source: enable USB remote wakeup of host mode.
- - mediatek,syscon-wakeup : phandle to syscon used to access the register
- of the USB wakeup glue layer between SSUSB and SPM; it depends on
- "wakeup-source", and has two arguments:
- - the first one : register base address of the glue layer in syscon;
- - the second one : hardware version of the glue layer
- - 1 : used by mt8173 etc
- - 2 : used by mt2712 etc
- - mediatek,u3p-dis-msk : mask to disable u3ports, bit0 for u3port0,
- bit1 for u3port1, ... etc;
-
-additionally the properties from usb-hcd.yaml (in the current directory) are
-supported.
-
-Sub-nodes:
-The xhci should be added as subnode to mtu3 as shown in the following example
-if host mode is enabled. The DT binding details of xhci can be found in:
-Documentation/devicetree/bindings/usb/mediatek,mtk-xhci.txt
-
-The port would be added as subnode if use "usb-role-switch" property.
- see graph.txt
-
-Example:
-ssusb: usb@11271000 {
- compatible = "mediatek,mt8173-mtu3";
- reg = <0 0x11271000 0 0x3000>,
- <0 0x11280700 0 0x0100>;
- reg-names = "mac", "ippc";
- interrupts = ;
- phys = <&phy_port0 PHY_TYPE_USB3>,
- <&phy_port1 PHY_TYPE_USB2>;
- power-domains = <&scpsys MT8173_POWER_DOMAIN_USB>;
- clocks = <&topckgen CLK_TOP_USB30_SEL>, <&clk26m>,
-<&pericfg CLK_PERI_USB0>,
-<&pericfg CLK_PERI_USB1>;
- clock-names = "sys_ck", "ref_ck";
- vusb33-supply = <&mt6397_vusb_reg>;
- vbus-supply = <&usb_p0_vbus>;
- extcon = <&extcon_usb>;
