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@xxxxxxxxxxx>. 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).
