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).
