How to use meta-adi with a board not in the list of supported boards

Category: Software

The meta-adi Yocto layers at meta-adi-xilinx and meta-adi-core advertise that they will provide a highly customized Analog Devices kernel for use with PetaLinux.

I have two different boards that are *not* listed in the table of supported Projects/Devicetrees in the at meta-adi-xilinx.  However we have our own Vivado 2021.2 HDL design based on the Analog Devices spi-engine and dmac framework for both ADCs and DACs.

I am having trouble understanding why meta-adi only supports a small list of known device trees.  I also don't understand the section "Adding a new Devicetree" in

  • Why would I need to delete *any* device tree nodes to use meta-adi? I'm going to want to use them!
  • Perhaps I don't understand the purpose of meta-adi.  Isn't it providing the kernel patches to support the enhanced IIO subsystem to support various Analog Devices device drivers with the HDL spi-engine framework for performance?
  • Why would kernel enhancements be specific to a set of known device trees?

Can anyone clarify this?

    I'm just not understanding why there would be any "redefinition" of device tree nodes.  The Xilinx device tree generator should generate nodes for all the IP during petalinux…
  • Interestingly, yesterday I removed the meta-adi-xilinx/recipes-bps/device-tree/device-tree.bbappend recipe. We have to append to the autogenerated device tree for our project anyway, so…
