On Exynos5420 we support 8 cpufreq steps (600-1300 MHz) for LITTLE and 12 steps for big core (700-1800 MHz). Add respective cooling cells.

Although the above two properties are defined they aren't parsed in the kernel. Setting min / max extents for cooling devices via cooling maps does work though. [...]
