No, it does not solve it. 1. Patchset goes via separate trees (DTS are always separate), so it is not bisectable. One of the branches/trees will have broken DTS.
2. All out of tree DTSes are broken. This is expressed as ABI and - with some reasonable exceptions - you should not break it. https://elixir.bootlin.com/linux/v5.19-rc1/source/Documentation/devicetree/bindings/ABI.rst
You have to keep backwards compatibility, so parse/handle both versions of DTS.
Best regards, Krzysztof
