Beyond having the document point to the existing DT binding documentation, I think this is a non-starter. It won't be helpful for anyone to have two separate repositories containing the same bindings. They will get out of sync and we will have pain as a result. For existing bindings we need to have a way to share the documentation, and I don't think we can even talk about whether it makes sense to migrate the documetation to the UEFI managed repo before the UEFI process is fully flushed out. g. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
