It's quite interesting work, it seems to be for a more advanced use case
where OPP voltage is being adjusted at runtime.

We could use it instead of removing an OPP and then adding with updated
voltage. On Exynos there is there is just a need to update OPPs once at boot
time, so it is more "static". However the requirements could presumably
change in future.

If that's your preference I could switch to that notifier approach.
AFAICS the API would still need to be extended to support multiple voltages,
when in future we add support for the Body Bias regulator.
