||||||
The device node for Mediatek USB3.0 DRD controller
|
|
||||||
|
|
||||||
Required properties:
|
|
||||||
- compatible : should be "mediatek,<soc-model>-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.
|
|
||||||
