Sorry, attached file didn't work, I'll try this:
/dts-v1/;
/ {
#address-cells = <0x1>;
#size-cells = <0x1>;
compatible = "avnet,microzed", "xlnx,zynq-7000";
model = "Test Device";
chosen {
bootargs = "earlyprintk";

The reason that the driver is not mainline is most likely
Simple solution would be to just stop using the cadence driver. There are
issues in the Zynq that cannot really be resolved in software apparently, and
the only way around them we've found is to just use a bitbang GPIO controller
on the same pins. That made all problems go away.

to me.
Kind regards, Arno
