Looks goot do me as well. Acked-by: MyungJoo Ham <myungjoo....@samsung.com> Anyway, for the sake of curiosity... Having suspend-frequency is usually required when the frequency configuration is reset with suspend-resume as older Exynos's CPU did (I don't know whether it still does). Does GPU do this as well? (memory-bus won't do this because they are kept turned on during suspend) Cheers, MyungJoo
