[PATCH V4 0/5] ARM: exynos: Add l2 retention mode cpuidle state

[amit.kachhap@linaro.org (Amit Daniel Kachhap)]

Changes since V3:
*Implemented Russell feedback and moved sleep magic 4byte memory before 
s3c_cpu_resume to data section.

Changes since V2:
*Implemented the suggestion of MyungJoo Ham and used INFORM0/1
registers for resume for some board versions.
*Added back save/restore through CPU PM notifiers as suggested by 
Lorenzo Pieralisi. This is useful to restore vfp state.
*some patch modularization (s5p/exynos) and proper commit logs.  

Changes since V1:
*rebased the whole patch against 3.2-rc1 tree
*removed GIC save/restore in AFTR cpuidle state as it is external
to cpu powerdomain
*Added L2 setup code through device tree
*Removed only l2 save/restore registers in sleep

This Patch series adds support for AFTR mode cpuidle state based on
patch (http://www.spinics.net/lists/arm-kernel/msg132243.html) earlier
submitted by Jaecheol Lee <jc.lee@samsung.com>.

This patch uses CPU PM notifiers , common l2 save/restore and
new cpu_suspend/resume interfaces and is based on the tip of
for-next branch of samsung tree.
(git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git for-next).
