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 at 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).
