|
|
|
|
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
|
|
|
|
"ref_clk" Clock source to core during PHY power down
|
|
|
|
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.
|
|
|
|
Example device node:
|
|
|
|
usb@0 {
|
|
#address-cells = <0x2>;
|
|
#size-cells = <0x1>;
|
|
status = "okay";
|
|
compatible = "xlnx,zynqmp-dwc3";
|
|
clock-names = "bus_clk" "ref_clk";
|
|
clocks = <&clk125>, <&clk125>;
|
|
ranges;
|
|
|
|
dwc3@fe200000 {
|
|
compatible = "snps,dwc3";
|
|
reg = <0x0 0xfe200000 0x40000>;
|
|
