Commit34962fb807
("docs: Fix more broken references") replaced the broken reference to rockchip,dwc3-usb-phy.txt binding for the Qualcomm DWC3 binding (qcom-dwc3-usb-phy.txt). That's wrong, so replace that reference for the correct ones. Fixes:34962fb807

Rockchip SuperSpeed DWC3 USB SoC controller
|
|
|
|
Required properties:
|
|
- compatible: should contain "rockchip,rk3399-dwc3" for rk3399 SoC
|
|
- clocks: A list of phandle + clock-specifier pairs for the
|
|
clocks listed in clock-names
|
|
- clock-names: Should contain the following:
|
|
"ref_clk" Controller reference clk, have to be 24 MHz
|
|
"suspend_clk" Controller suspend clk, have to be 24 MHz or 32 KHz
|
|
"bus_clk" Master/Core clock, have to be >= 62.5 MHz for SS
|
|
operation and >= 30MHz for HS operation
|
|
"grf_clk" Controller grf clk
|
|
|
|
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/phy-rockchip-inno-usb2.txt - USB2.0 PHY
|
|
Documentation/devicetree/bindings/phy/phy-rockchip-typec.txt - Type-C PHY
