1*4882a593SmuzhiyunXilinx SuperSpeed DWC3 USB SoC controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible:	Should contain "xlnx,zynqmp-dwc3"
5*4882a593Smuzhiyun- clocks:	A list of phandles for the clocks listed in clock-names
6*4882a593Smuzhiyun- clock-names:	Should contain the following:
7*4882a593Smuzhiyun  "bus_clk"	 Master/Core clock, have to be >= 125 MHz for SS
8*4882a593Smuzhiyun		 operation and >= 60MHz for HS operation
9*4882a593Smuzhiyun
10*4882a593Smuzhiyun  "ref_clk"	 Clock source to core during PHY power down
11*4882a593Smuzhiyun
12*4882a593SmuzhiyunRequired child node:
13*4882a593SmuzhiyunA child node must exist to represent the core DWC3 IP block. The name of
14*4882a593Smuzhiyunthe node is not important. The content of the node is defined in dwc3.txt.
