+Xilinx Zynq usb controller based on synopsys usb IP(v2.20a)

   s/usb/USB/.

+Required properties:
+- compatible:   should contain "xlnx,zynq-usb-2.20a"
+- clocks:       clock provider specifier
+- reg:          offset and length of the register set in the memory map
+- interrupt-parent: the phandle for the interrupt controller that services
+                    interrupts for this device.

This property has never been required -- it can be inherited from the upper level node.

WBR, Sergei
