2014-07-18 Thread Krzysztof Kozlowski
Enable ARMCLK down feature on all Exynos4 SoCs. The frequency of ARMCLK will be reduced upon entering idle mode (WFI or WFE). The feature behaves like very fast cpufreq ondemand governor. In idle mode this reduces energy consumption on full frequency chosen by cpufreq governor by approximately:
