I don't think that's this case. I'm not sure, if the basic midlevel
mechanism is understood: The midle level code expects that driver
start/stop the stream in the trigger callback, so if you can queue
more 'periods' into the DMA engine, do it and abort/pause the transfer
only the trigger callback request. You don't need to check appl/hw_ptr
in the lowlevel code.
