We need to keep the solution without DSP, so we can replace DSP
solution with non-DSP when it's required. But when we introduce SOF for
DSP control, there will be more routes in machine driver and device
tree usage is different from the original. So it's hard to share the
same driver for these two solutions.
Thanks,
Trevor
