[PATCH v3 0/4] ARM: EXYNOS: cpuidle: fix AFTR mode on boards with secure firmware enabled

From: Bartlomiej Zolnierkiewicz
Date: Wed Jul 09 2014 - 13:19:17 EST


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).

- rebased on top of next-20140708 +
(with rejects fixed)
(with rejects fixed in patch #2)
- addressed review comments from Tomasz Figa and Daniel Lezcano
