Subject: [PATCH 3/3] ARM: EXYNOS: cpuidle: Allow C1 state only in supported SOC's.
Date: Thu, 14 Mar 2013 11:32:59 +0530	[thread overview]
Message-ID: <1363240979-1939-4-git-send-email-amit.daniel@samsung.com> (raw)
In-Reply-To: <1363240979-1939-1-git-send-email-amit.daniel@samsung.com>

This patch registers the basic C0 state for all exynos SOC's but
limits the C1(AFTR -Arm off top running) state in only the supported
SOC's(ie. EXYNOS 4210, 4212, 4412 and 5250).
