Hi Lukasz,
Please post including MLs, even resending.
Will apply for v3.19, and just note that you asked me to apply this for 3.18 in personal talk but I couldn't see any requirements for fixes-3.18. If I'm missing something, please let me know.
Thanks,
Kukjin

The thing is that by default Exynos 4412 (trats2) can run with modified cpufreq to support SW governed overclocking (BOOST).
To provide safe BOOST operation, TMU (thermal) _must_ be configured. Configuration is not possible when trats2 DTS lacks of those patches.
So, yes there is a requirement to add those patches to v3.18 (if not possible please add it to v3.19).

Well, AFAIK the BOOST mode is only available on only Samsung mobile not mainline and so I think this is not for bug fix in mainline for 3.18...
