+Required properties:
+- compatible : Should be "xlnx,axi-usb2-device-4.00.a"
+- reg : Physical base address and size of the Axi USB2
+ device registers map.
+- interrupts : Property with a value describing the interrupt
+ number.
+- interrupt-parent : Must be core interrupt controller
+- xlnx,include-dma : if DMA is included
+
+Example:
+ axi-usb2-device@42e00000 {
+ compatible = "xlnx,axi-usb2-device-4.00.a";
+ interrupt-parent = <0x1>;
+ interrupts = <0x0 0x39 0x1>;
+ reg = <0x42e00000 0x10000>;
+ xlnx,has-builtin-dma;
+ };
