[PATCH] PM / devfreq: Generic cpufreq governor

2018-07-27 Thread Saravana Kannan
Many CPU architectures have caches that can scale independent of the CPUs. Frequency scaling of the caches is necessary to make sure the cache is not a performance bottleneck that leads to poor performance and power. The same idea applies for RAM/DDR. To achieve this, this patch adds a generic dev
