Merge tag 'exynos-cpuidle' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/soc
Merge "Samsung exynos cpuidle update for v3.17" from Kukjin Kim:
- add callbacks exynos_suspend() and exynos_powered_up()
for support cpuidle through mcpm
- skip exynos_cpuidle for exynos5420 because is uses
cpuidle-big-liggle generic cpuidle driver
- add generic functions to calculate cpu number is used
for pmu and this is required for exynos5420 multi-cluster
- add of_device_id structure for big.LITTLE cpuidle and
add "samsung,exynos5420" compatible string for exynos5420
* tag 'exynos-cpuidle' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
ARM: EXYNOS: populate suspend and powered_up callbacks for mcpm
ARM: EXYNOS: do not allow cpuidle registration for exynos5420
cpuidle: big.LITTLE: init driver for exynos5420
cpuidle: big.LITTLE: Add ARCH_EXYNOS entry in config
ARM: EXYNOS: add generic function to calculate cpu number
cpuidle: big.LITTLE: add of_device_id structure
+ Linux 3.16-rc5
