Hi Bartlomiej,
I tested this patch-set for AFTR mode.
When CPU1 is offline state, I checked that CPU0 enter the AFTR mode.

My apologies for the double-post; the previous patch lacked an Acked-by and
several important recipients. Keep me on the CC list as I'm not subscribed to

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).

AFTR mode support brings reduced energy consumption and is
a prerequisite for more advanced W-AFTR/LPA power saving modes.
AFTR mode has been already supported on other Exynos SoCs for
few years and this patch adds its support for Exynos3250 SoC.
The differences in Exynos3250 SoC AFTR mode suppor

Hi,
The following patchset adds coupled cpuidle support for Exynos3250
to an existing cpuidle-exynos driver. As a result it enables AFTR
mode to be used by default on Exynos3250 without the need to hot
unplug CPU1 first.
The patchset depends on:
- for-next branch (commit: 77105c882ba6) of linux-
There is a kernel message about secondary CPU bootup when
exynos_core_restart() is called through CPU hotplug code-path
(the only exynos_core_restart() user currently) so there is no
need for an extra info on Exynos3250 SoC about software reset.
This also prepares exynos_core_restart() to be re-use
Add get_cpu_boot_addr() firmware operation and then
exynos_get_boot_addr() helper.
This is a preparation for adding coupled cpuidle support
for Exynos3250 SoC.
There should be no functional changes caused by this patch.

Hello Javier,
I noticed that this recent commit breaks rtc-s3c on my Odroid-X2

board files based on exynos4, and using the rtc-s3c, are now required to

HS400 timing values are added for SMDK5420, exynos5420-peach-pit
and exynos5800-peach-pi boards.
This also adds RCLK GPIO line, this gpio should be in pull-down
state.
This also enables HS400 on peach-pi and this updates the clock frequency
to 800MHz to be set as input clock t
Odroid X2/U3 sound support can now be specified in device tree using
