I agree.  I'll send out V4 this coming week with the clk rate change
notifiers rolled in.  That means that there won't be any missing
pieces for my vision of how a complex clk tree should interact with
drivers.  If it is not what people want then we can probably de-scope
pieces of it, but I think the architecture is sound.

Thanks for reviewing Shawn.
