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

From: Bartlomiej Zolnierkiewicz
Date: Mon Sep 07 2015 - 11:45:39 EST


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.
