I understand this does not differ per board, because it is component of
the SoC, yet still I do not see any value in enforcing name.

Yeah, the dai-common $ref is correct, so you should not need it. Do you
see any warning?

I claim nothing has to be done and entire patch is redundant or not much
helpful. Your commit msg did not explain *why* this is needed and what
problem you are fixing, so what I can say? I don't know why should be
aligned because I do not understand the problem being fixed.
