Subject: [PATCH v6 0/5] ARM: EXYNOS: cpuidle: fix AFTR mode on boards with secure firmware enabled
Date: Fri, 05 Sep 2014 15:51:23 +0200 [thread overview]
Message-ID: <1409925088-4705-1-git-send-email-b.zolnierkie@samsung.com> (raw)
Hi,
This patch series adds support for AFTR idle mode on boards with
secure firmware enabled and allows EXYNOS cpuidle driver usage on
Exynos4x12 SoCs.
It has been tested on Trats2 board (using Exynos4412 SoC with secure
firmware enabled) on which AFTR mode reduces power consumption by ~12%
when EXYNOS cpuidle driver is enabled (in both cases the default
exynos_defconfig config is used and CPU1-3 are offlined).
Currently Exynos4412 SoC support is limited to Trats2 board.
Depends on:
- next-20140904 branch of linux-next kernel tree
- "irqchip: Properly fetch the per cpu offset" patch
(https://www.mail-archive.com/linux-kernel at vger.kernel.org/msg716674.html)
- [PATCH v3 0/5] Firmware-assisted suspend/resume of Exynos SoCs
(https://www.mail-archive.com/linux-samsung-soc at vger.kernel.org/msg35921.html)
Changes since v5:
- rebased on top of next-20140904 +
"irqchip: Properly fetch the per cpu offset" patch

[PATCH v2 0/2] Firmware-assisted suspend/resume of Exynos SoCs
(http://www.mail-archive.com/linux-samsung-soc at vger.kernel.org/msg34282.html)
- call exynos_save_cp15() only on A9 type core (this is needed for the future
Exynos3250 SoC support)
Changes since v3:
- rebased on top of next-20140804 +

- (re-)added patch fixing S5P_CENTRAL_SEQ_OPTION register setup
Changes since v2:
- rebased on top of next-20140708 +
[PATCH 5/6] ARM: EXYNOS: Fix suspend/resume sequencies
(http://www.mail-archive.com/linux-samsung-soc at vger.kernel.org/msg32809.html)
[with rejects fixed]
[PATCH 6/6] ARM: EXYNOS: Register cpuidle device only on Exynos4210 and 5250
(http://www.mail-archive.com/linux-samsung-soc at vger.kernel.org/msg32808.html)
[PATCH 0/2] Firmware-assisted suspend/resume of Exynos SoCs
(http://www.mail-archive.com/linux-samsung-soc at vger.kernel.org/msg32991.html)
[with rejects fixed in patch #2]
- addressed review comments from Tomasz Figa and Daniel Lezcano
Changes since v1:
- synced against next-20140602
- added missing Acked-by-s
