Subject: ARM: dts: add suspend opp to exynos4412
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1605b60ad064c7019db8ade07f0b7bdc8c197b93;p=openwrt%2Fstaging%2Fblogic.git

ARM: dts: add suspend opp to exynos4412

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.
