We had a discussion with Krzysztof about it, he agreed with this form of the
property.
My concern was that it's just too much typing, and makes little sense because
these
settings always go together. If register layout changes, or parameter set
changes in
incompatible way, then it's another device, not exynos-srom anymore.
So would you agree with that, or is your position strong?
