+Required properties:

+- reg			: Physical base address and size of the USB2
+			  device registers map.
+- interrupts		: Should contain single irq line of USB2 device
+			  controller
+- xlnx,has-builtin-dma	: if DMA is included
+
+Example:
+ 		axi-usb2-device@42e00000 {
+                        compatible = "xlnx,usb2-device-4.00.a";
+                        interrupts = <0x0 0x39 0x1>;
+                        reg = <0x42e00000 0x10000>;
+                        xlnx,has-builtin-dma;
