The goal is to be able to propagate digital configuration along audio
paths in much the same way as we currently do for power with DAPM.  Lars
did a presentation with a good writeup of a proposal for that at ELC-E a
few years ago.  Unfortunately the only person that is really able to
find time to work on this at the minute is Morimoto-san, this is what
his componentization changes are driving towards - part of the design is
that everything in the system will be a component and we can therefore
treat every device identically.
