From 1e9fec0e40deff9d18e4197b5f5f99f85f5d36a5 Mon Sep 17 00:00:00 2001 From: Amit Daniel Kachhap Date: Wed, 28 Aug 2013 00:48:24 +0900 Subject: ARM: EXYNOS: Skip C1 cpuidle state for exynos5440 This patch skips the deep C1(AFTR -Arm off top running) state for exynos5440 SoC as this soc does not support this state. The cpu's only allows the basic C0 state. The C1 state is filtered by re-initialising the driver state_count value to 1.
