I don't have strong opinion on that, but in my case, I was considering using a simple list instead of several nodes. I don't like having to add fake address just to ensure uniqueness.

Something like that:

sound-dais = <&spdif_codec 1>, <&hdmi 0>;

You are right, this would be simpler (I did not see that there could be phandle's with different cell sizes in a list).

That being said, it will require changing the name with a plural form, and ensuring we have the same number of parameters for each codec.

But I don't think that changing the name could be useful: the treatment is exactly the same and, as a result, all CODEC DAIs go to the DAI list of the DAI link.
