Merge tag 'samsung-drivers-soc-pmu-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into devel
Improvements for Exynos PMU driver for v4.11:
Beside basic function of setting proper configuration for low power modes, the
Exynos PMU (Power Management Unit) driver is also a provider of syscon regmap
for its registers. This regmap is essential to many other drivers wanting to
or needing to implement low power mode.
Exynos pinctrl driver, before getting support for Runtime Power Management,
needs access to this syscon regmap. Let's do it in a DT ABI friendly way.
