* ARM: EXYNOS: Fix suspend/resume sequencesTomasz Figa2014-08-091-21/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Due to recent consolidation of Exynos suspend and cpuidle code, some parts of suspend and resume sequences are executed two times, once from exynos_pm_syscore_ops and then from exynos_cpu_pm_notifier() and thus it breaks suspend, at least on Exynos4-based boards. In addition, simple core power down from a cpuidle driver could, in case of CPU 0 could result in calling functions that are specific to suspend and deeper idle states. This patch fixes the issue by moving those operations outside the CPU PM notifier into suspend and AFTR code paths. This leads to a bit of code duplication, but allows additional code simplification, so in the end more code is removed than added.
