Thanks for link.
For what kind of device do you wrote simple codec? We would use it for
GSM and BT
(we could use bt-sco driver) which produce PCM samples (rate is
determined by mclk and bclk).
If your proposal wasn't accepted then I think the best would be for
our purpose to write dummy codecs
for both interfaces and not generic simple codec.
