Maybe I think that we'd better add 'reg' properties to each port, however, there might be same matter in other SoCs, so I'm not sure whether your patch breaks the backword compatibility or our devicetrees are wrong.
I'd be glad if I could hear something about this issue from you.
There's an ongoing thread between Morimoto-san and Tony Lindgren around the graph card including this issue, there Morimoto-san proposed some code which would let the reg property be optional. Device trees should still be updated but that way we wouldn't actually break anything which would be good.
There's a patch now - "[PATCH][RFC] ASoC: simple-card-utils: fixup asoc_simple_card_get_dai_id() ID method".
