Not to say that I didn't wonder if we can perhaps simplify things some more and move BE declaration to topology and perhaps even implement generic i2s board. It is something to revisit.

My point is that the topology already provides the information for the DSP configuration and this is used for the codec configuration, but that's two pieces of information that need to match, and two things to change if for some reason you want to use different options.
