I know Mark had a preference to store DAI-specific data in sub-nodes rather than using this "[prefix]" thing... If that doesn't end up happening though, rather than "[prefix],", I think it'd be more typical to use "[prefix]-" since I've never seen a DT property name with two ","; "-" is typically used as the word separator in DT property names.
Hmm... If I can use sub-node, I can use below style for getting dai name ? I guess it is easy/simple, but, what do you think about this ?

If you want the "simple-audio" binding and driver to be completely generic, you had better name this node something generic like "codec".
simple-audio,codec;
Then, you wouldn't need that property to identify what type of child node this is.
simple-audio,dev = <&ak4642>;
Make that value <&ak4642 0> in order to select which AK4642 port you want to connect.

Name this node something generic like "CPU".
simple-audio,cpu; simple-audio,dev = <&sh_fsi2>; ...} }
