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 Signed-off-by: Olof Johansson <olof@lixom.net>
