This looks like a DPCM (Documentation/sound/alsa/soc/DPCM.txt) to me.

I'm not sure how to write a DT for DPCM either. But it seems that you might need a specific machine driver (guessing).

I saw Morimoto-san plans to add DPCM into Simple Card, but not sure when they will finish it. Otherwise, you may use Simple Card while following their defined DT formats.

Depending on what the system looks like it's not at all clear that there should be any visibility at all of DPCM in the DT - it's a detail of how Linux is implemented at the end of the day.
