We discussed this and yes we are looking at ways to solve this longer term with DAPM but today DAPM doesn't help us in managing DMAs for our controller. I believe Vinod did discuss this limitation during ELC. We are starting this discussion internally and will try to solve this part.

We discussed using CODEC-CODEC links for this. If you want to add DMA operations to them then that's a simple matter of programming (which IIRC we did discuss).

Now for us to mange the internal sinks and source how should we go about modelling them in DAPM and provide hw_params for the configuration?

In the same way as anyone not doing it on a SoC does; at the minute that means working out any settings that need configuration by looking at what happens when the signal goes out onto an audio interface. Ideally we'd have a mechanism for propagating digital configuration along audio paths.
