Merge tag 'exynos-mcpm-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/soc
Merge "Exynos 2nd MCPM updates for v3.16" from Kukjin Kim:
- enable mcpm for dual-cluster exynos5800
- since commit 166aaf39 ("ARM: 8029/1: mcpm: Rename the
power_down_finish() functions to be less confusing"),
use new member name wait_for_cpu_powerdown.
This is based on tags/exynos-mcpm.
Note that since the commit 166aaf39 is in rmk tree so this
should be sent to upstream after that in 3.16 merge window.
* tag 'exynos-mcpm-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
ARM: EXYNOS: mcpm rename the power_down_finish
ARM: EXYNOS: Enable mcpm for dual-cluster exynos5800 SoC
