| Qualcomm SuperSpeed DWC3 USB SoC controller |
| |
| Required properties: |
| - compatible: should contain "qcom,dwc3" |
| - clocks: A list of phandle + clock-specifier pairs for the |
| clocks listed in clock-names |
| - clock-names: Should contain the following: |
| "core" Master/Core clock, have to be >= 125 MHz for SS |
| operation and >= 60MHz for HS operation |
| |
| Optional clocks: |
| "iface" System bus AXI clock. Not present on all platforms |
| "sleep" Sleep clock, used when USB3 core goes into low |
| power mode (U3). |
| |
| 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/qcom,dwc3-usb-phy.txt |
