Hi,

Currently, there's no supported way of doing that. However, it is something that makes sense to add, so we have to think in some mechanism to extend ADI devicetrees. What you can try, to just go on, is:

• Use your dtsi as dts and include the zynqmp-zcu102-rev10-adrv9009.dts there;

• Put your dts in path-to-your-project/project-spec/meta-user/recipes-bsp/device-tree/files/ and rename it system-user.dtsi. This overwrites the file in this location;

• on the device-tree.bbappend file, comment the line cp "${DTS_INCLUDE_PATH}/${KERNEL_DTB}.dts" ${WORKDIR}/system-user.dtsi;

• Not sure if you need to remove the devicetree node for your interrupt IP. But if you do, use the same logic as in the pl-delete-nodes-* files (in your case, you can just add a delete-node line in your new .dtsi file before defining your dts properties). You need to do this if you are defining a node in your .dtsi file which gets defined by the petalinux devicetree auto generation mechanism. Check the components/plnx_workspace/device-tree/device-tree/pl.dtsi file to see if your node gets defined.

Note that, I'm not sure if this will work but its worth a try if you are in a hurry. If not, keep an eye on the repo and wait for support.

Hope this helps!
