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/msg331100.html
Changelog is in respective patches.
Chander Kashyap (5):
driver: cpuidle-big-little: add of_device_id structure
arm: exynos: add generic function to calculate cpu number
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

This driver will be used by many big.Little Soc's. As of now it does
string matching of hardcoded compatible string to init the driver. This
comparison list will keep on growing with addition of new SoC's.
Hence add of_device_id structure to collect the compatible strings of
SoC's using this driver.

The address of cpu power registers in pmu is based on cpu number
offsets. This function calculate the same. This is essentially
required in case of multi-cluster SoC's e.g Exynos5420.
