+Cavium SuperSpeed DWC3 USB SoC controller
+
+Required properties:
+- compatible: Should contain "cavium,octeon-7130-usb-uctl"
+
+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.
