Doesn't look good here. Do you have the latest version of the driver?

Have you checked the values? There is surely
#address-cells = <1>;
#size-cells = <0>;
missing here, but that shouldn't cause your problems IMHO. I probably can't
help any further, never used Xilinx so far (you have the newest version of the
dts-generator?).
