- I now know how the changing voltage API works
   - What I don't know is where we'd call it from to initialise them
   - Can we do that from the ab8500 regulator driver's init() or probe()?

I'm surprised you've managed to miss the existing interfaces:

    include/linux/regulator/machine.h
    Documentation/devicetree/bindings/regulator/regulator.txt

I saw the interfaces, I just don't know what's the correct thing to
do. I'm leaving Device Tree for the moment. I'm more concerned about
addressing the problem in the AB8500 Regulator Driver and it's
Platform counterpart.

The only thing of interest that I could see was the regulator_init()
call-back. Is this what you were alluding to in the first link?

No.  apply_uV.

Ah, nice.

So is it worth me making at least those changes, so we can start 
thinning down our platform data overhead?
