Hi Cody,

Thanks for patch. The device tree in meta-xilinx is likely to be
removed in the future due to the kernel providing a microzed device
tree in v4.10 and newer.

However to sort this out now for master and morty, we can just replace
the device tree in meta-xilinx with the kernel one. However I just
want to confirm that it solves your issue before I go ahead and make
the change.

Grab the device tree here:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/plain/arch/arm/boot/dts/zynq-microzed.dts

And copy the content into the device in the meta-xilinx layer, rebuild
and let me know if it also solves the issue.

Thanks,
Nathan
