My patch for adding avnet prefix to kernel was accepted.
That's why use:
model = "Avnet Zynq MiniZed Development Board";
compatible = "avnet,minized", "xlnx,zynq-7000";

Please check other boards. This ulpi-phy is just in Xilinx git repo.

This is not the part of binding.

this is not the part of kernel intc binding doc.
It looks like qemu binding.

please use "fixed-partitions" here.

remove 0x from node name and the same below.
