It can often happen that bindings are merged No one claimed it will guarantee that and no one even suggested that. Submitting patches even describes this... > alone into a release.

No one would be bothered to submit a bindings > if the DTS using the bindings is only kept out of tree. I would be bothered. I don't want to maintain unused (unused as in upstream) ABI. I don't care about such ABI for downstream users and no one in upstream should spend any precious cycles on reviewing something which serves no upstream purposes. > > In short, there will be Nord DTS using the binding coming, and I do not Maybe there will, maybe there will not. > think posting them at the same time should be a requirement. Well, it is a requirement as I explained previously, said that *multiple* times on the mailing list, documented expectations in mentioned/linked email threads. It's also documented in submitting patches in DT (although not with that strong wording). Best regards, Krzysztof
