This driver is mainly used for setting misc bits of register from PMU IP
of Exynos SoC which will be required to configure before Suspend/Resume.
Currently all these settings are done in "arch/arm/mach-exynos/pmu.c" but
moving ahead for ARM64 based SoC support, there is a need of DT based
implementation of PMU driver.
This driver uses already existing DT binding information.

While you are moving pmu.c from arch/arm/mach-exynos/ why NOT move
pm.c also along, with this we can completely get rid of is_soc_*()
checks. Please see comments [1] from Tomasz figa for my PMU series on
5420 and 5260.

[1] http://www.spinics.net/lists/arm-kernel/msg322724.html

We thought of it, but as you know "arch/arm/mach-exynos/pm.c" has a lot
of dependencies, not only on "mach/exynos" header files but also on "plat-samsung".
Also we need to decide proper location for pm.c, I can think for "drivers/soc", what do you say?

Seeing that there is a significant amount of work, we decided to keep this work
as separate from pmu.c work.  May be after this patch we can start work on it.
