Amlogic Meson GX DWC3 USB SoC controller
|
|
|
|
Required properties:
|
|
- compatible: depending on the SoC this should contain one of:
|
|
* amlogic,meson-axg-dwc3
|
|
* amlogic,meson-gxl-dwc3
|
|
- clocks: a handle for the "USB general" clock
|
|
- clock-names: must be "usb_general"
|
|
- resets: a handle for the shared "USB OTG" reset line
|
|
- reset-names: must be "usb_otg"
|
|
|
|
Required child node:
|
|
A child node must exist to represent the core DWC3 IP block. The name of
|
|
the node is not important. The content of the node is defined in dwc3.txt.
|
|
|
|
PHY documentation is provided in the following places:
|
|
- Documentation/devicetree/bindings/phy/meson-gxl-usb2-phy.txt
|
|
- Documentation/devicetree/bindings/phy/meson-gxl-usb3-phy.txt
