From the information I can find, it looks as if most of the machinery required to implement it is already in dtc, so it should (hopefully) just be a matter of adding a new keyword to detect plugins, a scan to find the cross-references (or possibly reusing the existing one) and then a little bit of extra logic. > > https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/overlay-notes.txt > has the specs. Hmm, that’s even less complete than the docs that I’d found. From that, it seems as if the only thing that dtc needs to do is support the /plugin/ syntax and emit a section describing unresolved references? Or is dtc also expected to be able to do the merging?
