The driver waits for an interrupt to stop the stream in a known state after a frame. If rkisp1_cap_stream_disable() is called after stopping the rest of the pipeline, then most likely the interrupt won't arrive, we'll get a timeout and debugfs variables mp_stop_timeout or sp_stop_timeout will be incremented.
