[RESEND PATCH v2] ARM: exynos4: hotplug: Fix CPU idle clock down after CPU off

2014-07-16 Thread Krzysztof Kozlowski
On Exynos4 USE_DELAYED_RESET_ASSERTION must be set in ARM_COREx_OPTION register during CPU power down. This is the proper way of powering down CPU on Exynos4. Additionally on Exynos4212 without this the CPU clock down feature won't work after powering down some CPU and the online CPUs will work
