#1220988 — [PATCH v5 0/4] cpufreq-dt: add suspend frequency support

Hi,

This patch series adds suspend frequency support (using opp-v2
bindings and suspend-opp functionality) to cpufreq-dt driver and
then adds suspend opp for Exynos4412 based boards.

This patch series fixes suspend/resume support on Exynos4412
based Trats2 board and reboot hang on Exynos4412 based Odroid
U3 board.

Changes since v4:
- removed superfluous CONFIG_PM ifdefs
- added Acked-by tag from Krzysztof to patch #4
- added Acked-by tag from Viresh to patches #1-3

Changes since v3:
- fixed dev_pm_opp_get_suspend_opp() locking
- shortened variable name in dev_pm_opp_get_suspend_opp()
- adjusted cpufreq_generic_suspend() to work with cpufreq-dt
- removed no longer needed cpufreq_dt_suspend()
- added Acked-by tag from Viresh to patch #4

Changes since v2:
- rewrote to use suspend-opp functionality

Changes since v1:
- removed superfluous ";"

Depends on:
- next-20150902 branch of linux-next kernel tree

I've queued up [1-3/4] for the next PM pull request.

The [4/4] has to go in separately through the platform tree.

Thanks,
Rafael

Dear Rafael,

If you want, the fourth patch can go now through your tree - the late
SoC changes were pulled by Linus. No difference... I can grab it as I
had other DT related fix in queue.

The only important thing is to get entire patchset to 4.3 because it is
a fix for regression introduced in cpufreq for exynos. Do you plan to
send your part in current 4.3 cycle?

Best regards,
Krzysztof

The first 3 patches are already part for 4.3-rc1 and so you can keep
the DT update in your tree now. :)

Damn it, I missed it. It solves everything, the fourth patch will go
through platform tree.

Krzysztof
