Subject: [PATCH v4 5/5] ARM: EXYNOS: cpuidle: allow driver usage on Exynos4x12 SoCs
Date: Mon, 04 Aug 2014 19:45:45 +0200	[thread overview]
Message-ID: <1407174345-31213-6-git-send-email-b.zolnierkie@samsung.com> (raw)
In-Reply-To: <1407174345-31213-1-git-send-email-b.zolnierkie@samsung.com>

Register cpuidle platform device on Exynos4x12 SoCs allowing EXYNOS
cpuidle driver usage on these SoCs.

AFTR mode reduces power consumption on Trats2 board (Exynos4412 SoC
with secure firmware enabled) by ~12% when EXYNOS cpuidle driver is
enabled (in both cases the default exynos_defconfig config is used
and CPU1-3 are offlined).
