Hello Krzysztof/Kukjim,
CPUIdle seen to be not working for Exynos5422 Odroid boards.
Is their any way this feature will be implemented in the future.
Yeah a good willing to fix the bl1. More than one year asking for that !
nooo way !!
Your answer is at the end of

Thanks for the explanation.
I was just referring following the source code.
https://github.com/hardkernel/linux/blob/odroidxu3-3.10.y/arch/arm/mach-exynos/cpuidle-exynos5422.c
Ah, thanks for the pointer. So for my information, is that driver not
working with the exynos5422 ?
It seem that cpufreq and cpuidle go hand in hand.
At the first glance, there is a dependency with the cluster power state.
It is not allowed to enter the cluster power down if another subsystem
deny it. The driver itself is a pack of hacks based on cpuidle legacy
code and wildly backported from older kernels with arbitrary latency and
residency values.
