#1220286 — [PATCH v4 4/4] ARM: dts: add suspend opp to exynos4412

FromBartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>
Date2015-09-07 17:50 +0200
Subject[PATCH v4 4/4] ARM: dts: add suspend opp to exynos4412
Message-ID<q66Q9-1px-15@gated-at.bofh.it>
Mark 800MHz OPP as a suspend opp for Exynos4412 based
boards so effectively cpufreq-dt driver behavior w.r.t.
suspend frequency matches what the old exynos-cpufreq
driver has been doing.

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