Another small thing, that I just noticed, is this list. It forces
the first input source to be the output source without giving any
chance. I feel that we could have some flexibility here: one node
for two input sources, and one node for the output source.

Well, there is no critical problem with the current binding since
it follows the SoC design. Yet I doubt if this routing logic will
never break.

Any suggestion, Rob?
