the multi-cpu part is required for SoundWire, but the directions taken 
to support multi-cpu are changing due to additional developments in the 
MIPI Software WG (contributors only at this point). So the plan for now 
is to develop with single cpu-dai first, and add multi-cpu support at a 
later stage.

In other words, the multi-cpu/multi-link part isn't the most urgent 
priority and it shouldn't impact your work.

yes that's fine, this plan works fine for me.

there are only 2 or 3 cases of this snd-soc-dummy platform and I'll try 
to remove it as part of the first batch. I don't think it's necessary at 
all.

Thanks!
