Looks good to me.
Myungjoo, shall I take DT changes in this series into Samsung tree?
4/7 ARM: dts: Add PPMU dt node for Exynos3250 SoC
5/7 ARM: dts: Add PPMU dt node for Exynos4 SoCs
6/7 ARM: dts: exynos: Add PPMU node for Exynos3250-based Rinato/Monk board
7/7 ARM: dts: exynos: Add PPMU node for Exynos4412-based TRATS2 board
Thanks,
Kukjin
