Something like this would certainly be very useful for audio clocking if
it could be made to fit - that can get complex, is partly off-SoC and
frequently has multiple interrelated clock sources available, often with
various hard to describe interdependencies with constraints coming from
multiple sources and changing dynamically at run time.

In general your problem statement looks fairly sane.  I've not reviewed
this in detail but do think you should have a look at the OMAP stuff.

One thing to watch out for is that you'll find clocks doing things like
originating in one chip, going through another and being fed back into
the original chip.
