|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should contain "xlnx,zynqmp-dwc3"
|
||
|
|
- clocks: A list of phandles for the clocks listed in clock-names
|
||
|
|
- clock-names: Should contain the following:
|
||
|
|
"bus_clk" Master/Core clock, have to be >= 125 MHz for SS
|
||
|
|
operation and >= 60MHz for HS operation

|
|
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.
|
||
|
|
|
||
|
