See > https://members.openpowerfoundation.org/document/dl/469. there is discussion happened in Documentation patch (PATCH 2/4), whether to go with associativity based dt binding or not. https://patchwork.ozlabs.org/patch/507536/ it seems this binding may not map or will be complex representation for numa topologies like mesh, ring topologies which are used in upcoming arm64 numa platforms(as Mark Rutland pointed out). in this regard, i have proposed new binding, which will be based on associativity and acpi. This binding will serve wide range of arm64 platforms. i am waiting for review comments for the proposal, however i can post next version of patchset with new proposal implemented. > > Also, since this series is from August, any chance to post another and > incorporate the feedback provided so far? > > -- > Catalin thanks Ganapat -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
