AD9361 driver integration into Petalinux 2017.4

I am part of a team working on a product containing an AD9361. It is a custom board with a Xilinx ZynqMP Ultrascale+ ZU9 SoC. Due to the nature of the project and our customers we are locked in to using Xilinx Petalinux (currently 2017.4). We are having some trouble figuring out how to integrate the Analog Devices iio drivers into the Petalinux Kernel. Based on the documentation in your Analog Devices Linux repo, it appears that your 2018_R1 branch is based on Xilinx Petalinux 2017.4 (and therefore, based on Linux kernel 4.9.0). However, there appears to be a significant amount of change in your 2018_R1 branch from Xilinx Petalinux 2017.4. We would like some assistance in figuring out which new files and file changes we need to incorporate into our Petalinux, and any additional guidance you can provide in integrating the AD9361 into our environment. We will also be trying to integrate libiio with the goal of getting gnuradio running on the system.
