Merge tag 'samsung-drivers-4.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/drivers
Pull "Samsung drivers/soc update for v4.9" from Krzysztof Kozlowski:
1. Allow compile testing of exynos-mct clocksource driver on ARM64.
2. Document Exynos5433 PMU compatible (already used by clkout driver and more
will be coming soon).
