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
