This patch series contains improvements and changes needed to get a stable value of current CPU frequency from "cpuinfo_cur_freq" sysfs node in Tegra241 SoC. All the CPU's in Tegra241 implement the ARM Activity Monitor Unit (AMU). On reading the sysfs node, the frequency value is re-constructed using AMU counters.
