    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.
