 I looked at those patches, IMHO they are too large for doing too small thing. What they do is basically describing two registers one-by-one and adding a separate per-register driver. Isn't it too much just for pushing a reset pin?
 May be we should just invent some generic "compatible" string, like "samsung,exynos-pmu" (or "Samsung,exynos-pmu-generic", if you want to be more specific), which would do the same as my patch currently does? This would be only several lines of code, achieving the same result.
