I don't see any bus, so how does it work? How do you get the voice data
from it? I also do not see any DAI: neither here nor in the driver...

If there is going to be any new version, then implement all following
comments:

A nit, subject: drop second/last, redundant "bindings for". The
"dt-bindings" prefix is already stating that these are bindings.
