Will take care. The motivation came when I tried to used reboot/poweroff on exynos7, and since exynos7 has not added/enabled PMU and does not have access to arch/arm/mach-exynos, so option are to have a reboot/restart driver or we move pmu.c out of mach-exynos. I know there where some effort in past to move pmu.c to drivers, but I feel that is still WIP. And then I came across this generic syscon regmap based driver which are already in place, so just used it.
