Exynos5420 is a big-little Soc from Samsung. It has 4 A15 and 4 A7 cores.
This patchset adds cpuidle support for Exynos5420 SoC based on
generic big.little cpuidle driver.
Tested on SMDK5420.
This patch set depends on:
1. [PATCH 0/5] MCPM backend for Exynos5420
http://www.spinics.net/lists/arm-kernel/msg327923.html
2. [PATCH] arm: exynos: add generic function to calculate cpu number
http://www.spinics.net/lists/linux-samsung-soc/msg29446.html
http://www.spinics.net/lists/arm-kernel/msg324024.html
Changelog is in respective patches.
Chander Kashyap (5):
driver: cpuidle-big-little: add of_device_id structure
cpuidle: config: Add ARCH_EXYNOS entry to select cpuidle-big-little
driver
driver: cpuidle: cpuidle-big-little: init driver for Exynos5420
exynos: cpuidle: do not allow cpuidle registration for Exynos5420
mcpm: exynos: populate suspend and powered_up callbacks
