It was never intended that it is possible to bind a component to multiple cards. That it was possible was a bug that was overlooked and some people tried to do it which caused apparently random crashes later on, caused by the data structure corruption. This is why we added the check to catch this kind of mistake early and to avoid the crashes.
This is true, but I do think it's something that we should have some story on supporting for some of this hardware that has a bunch of channels in one IP block that can't really interact with each other. It's going to make it a lot easier for people to think about the hardware and how to describe it.
Yes, and if in some cases we must use multiple cards, it seems the only option left is to separate an ASoC platform driver into multiple drivers. It does not make sense to me since there is only one HW block.
