Date: Wed, 14 May 2014 13:33:56 +0530 [thread overview]
Message-ID: <1400054637-21505-6-git-send-email-chander.kashyap@linaro.org> (raw)
In-Reply-To: <1400054637-21505-1-git-send-email-chander.kashyap@linaro.org>
Exynos5420 is big.Little Soc. It uses cpuidle-big-litle generic cpuidle driver.
Hence do not allow exynos cpuidle driver registration for Exynos5420.
