In order to implement sub-stream multiplexing as a part of single BE DAI I have following observations.
I'm not quite sure what you mean here? Do you mean mixing or something else?
- All BE DAI ops gets called only once even if two different FE DAIs are
connected to a BE DAI. 2. BE DAI ops are always called with sub-stream 0.
are these expected ?
What is the best way to allow calling of BE DAI ops with different sub-stream ID so that I can do link configuration based on sub-stream parameters ? can you give some pointers ?
I think that's all what is supposed to happen with DPCM - it really only understands one stream with one configuration per DAI, it's expecting everything to get combined with mixers rather than TDM.
