I don't understand how can you guarantee for every possible future device to have always cells=0. If that's the case then indeed you do not need cells, but this needs explanation. You are designing now entire ABI, so you must design it fully, not just "works for me now". Lack of complete DTS - nothing here, nothing in the changelog - is IMO reason to NAK this patchset completely, also for reason me guessing the entire design instead of seeing the big picture.
