We have DT binding for the Exynos power domains:
Documentation/devicetree/bindings/arm/exynos/power_domain.txt
In fact the IO memory regions used in the power domain bindings
fall within the (sparse) PMU registers region.

There is also DT binding for the PMU subsystem:
Documentation/devicetree/bindings/arm/samsung/pmu.txt

I guess a platform device driver in drivers/power would be a better
fit than drivers/mfd. I doubt introducing an mfd driver now makes
much sense, we have already DT bindings for PHYs, the power domains,
etc.
