Hi, This patch series adds support for AFTR idle mode on boards with secure firmware enabled and allows EXYNOS cpuidle driver usage on Exynos4x12 SoCs.
It has been tested on Trats2 board (using Exynos4412 SoC with secure firmware enabled) on which AFTR mode reduces power consumption by ~12% when EXYNOS cpuidle driver is enabled (in both cases the default exynos_defconfig config is used and CPU1-3 are offlined).
