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).


Hi Bartlomiej,

what is the status of this patchset ? Is it supposed to land for 3.17 ?

I posted v4 yesterday:

When it comes to merging the patchset for 3.17 it is up to Kukjin.

Ok, thanks for the sync up.
