Here is the manual for the IP : http://www.xilinx.com/support/documentation/ip_documentation/axi_usb2_device/v5_0/pg137-axi-usb2-device.pdf This driver works with PLB IP version that's why maybe make more sense to use skip axi from compatible string and use just xlnx,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. > > Describe what this logically is.
