Is this not just a normal CODEC connected to a back end on a DPCM system? What are a "dynamic DAI" and "static DAI"? Your changelog is very unclear, I really can't tell from your changelog what this is aiming to do or how it proposes to do it.
The issue is basically if you have a path with a DPCM DAI at the front, but then a regular CODEC to CODEC DAI link later in the path. Say for example a CODEC attached to a CPU that uses DPCM but then the path goes through a CODEC to CODEC link to a speaker AMP after the CODEC.
I'm also concerned that nobody else seems to be seeing this, that's a bit of a warning sign that you might be misusing things here. Your mention of a "Codec to Modem link" sounds like you might be trying to use DPCM for off-SoC components somehow which is just not something that's expected to work.
At a minimum this needs a much better changelog.
Piotr is on holiday this week but should be back start of next week, so should be able to respin the patch then. For what its worth though I have seen this warning on other systems from the one he is working on as well.
Thanks, Charles
