Dear Rafael,

If you want, the fourth patch can go now through your tree - the late
SoC changes were pulled by Linus. No difference... I can grab it as I
had other DT related fix in queue.

The only important thing is to get entire patchset to 4.3 because it is
a fix for regression introduced in cpufreq for exynos. Do you plan to
send your part in current 4.3 cycle?

Best regards,
Krzysztof
