don't you need a .prepare to deal with suspend-resume?
DSP based solution is not implemented yet. As per our understanding In .prepare () callback, there is no extra logic needs to be implemented. Because of it, we have dropped .prepare() callback.
You don't need any logic IF the IP keeps its context while suspended. That wasn't the case for us, we had to re-program the registers when resuming.
In our case, IP keeps its context while suspend. No need to implement .prepare() callback.
