Subject: [PATCH v4 0/4] ARM: EXYNOS: cpuidle: add AFTR mode support for
 Exynos3250

Hi,

This patch series adds support for AFTR idle mode on boards with
Exynos3250 SoC and allows EXYNOS cpuidle driver usage on these
boards.

It has been tested on Samsung Rinato board (Gear 2).

Depends on:
- for-next branch (commit: 77105c882ba6) of linux-samsung.git
  kernel tree

Changes since v3:
- enhanced patch description for patch #1
- added Reviewed-by/Tested-by tags from Krzysztof
- enhanced C2_STATE BOOT mode flag comment
- moved exynos_{set,clear}_boot_flag() to firmware.c
- added patch description to patch #3

Changes since v2:
- rebased on top of for-next branch (commit: 77105c882ba6) of
  linux-samsung.git kernel tree

Changes since v1:
- rebased on top of for-next branch (commit: ce275c369a0b) of
  linux-samsung.git kernel tree
- fixed lockup on hotplug by using dsb_sev() instead of IPI in
  exynos_boot_secondary() on Exynos3250

Best regards,
