Hi Krzysztof, http://lxr.free-electrons.com/source/Documentation/devicetree/bindings/cpufreq/cpufreq-dt.txt http://lxr.free-electrons.com/source/Documentation/devicetree/bindings/thermal/thermal.txt#L201 These two documents provide the description on cooling-min-level and cooling-max-level. I will correctly update the value in the next updated patch. -Anand Moon -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
