[PATCH v4 0/4] cpufreq-dt: add suspend frequency support

From: Bartlomiej Zolnierkiewicz
Date: Mon Sep 07 2015 - 11:42:51 EST


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 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
