So, Liam already sent a message explaining the technical side of this -
the audio subsystem needs to glue together two or more components that
don't immediately have anything to do with each other from a device tree
point of view and may have rather complex interrelationships.

I'd just like to add that I *really* want to see you guys come to some
sort of firm and documented conclusion about the way to handle
situations like this.  Some variant of this seems to come up every
single time anyone tries to do anything to do with audio on a system
using the device tree and it's getting really repetitive.  What would be
really useful for audio at this point would be if we could get some sort
of decision about how to represent this stuff which we can point people
at so that work on systems using the device tree can be done without
having to deal with the device tree layout discussions that frequently
seem to be involved.
