Nit: Here is empty line at the end of file which I have removed.

I can't see any issue with this dts file.
Rob: I have added it to my zynq/dts branch. If you see any issue please
let us know.

https://github.com/Xilinx/linux-xlnx/tree/zynq/dt

Anton: Will be also good to update u-boot dts file with this one.

Thanks,
Michal
