PS19: 
It would still be a mess because you would have to specify how to handle the register value somehow, and have about half a dozen Kconfig options per register...

Quoting myself:
> I would copy the functions you need for now. Yes, it's code duplication, but it's easier to evaluate whether code reuse is possible this way.
