Hmm, it is difficult to explain via text...

On rsnd case, how many DAIs exist is based on the board,
and its connection (= R-Car SoC).
But FSI has fixed DAIs (= SH), thus having #sound-dai-cells
on SoC is not strange (= r8a7740/sh73a0).

And I'm not sure how it works on r9a07g0xx,
it is not my drivers.

Thank you for your help !!

Best regards
