Merge tag 'samsung-drivers-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/drivers

Merge "Samsung 2nd drivers for 3.16" from Kukjin Kim:

This is including fix exynos cpufreq driver compilation with
ARCH_MULTIPLATFORM. Even though this is a work around, this
is required for support exynos multiplatform for a while and
will be updated in near future.

This is based on tags/samsung-exynos.
