[PATCH V5 2/2] cpufreq: CPPC: Add support for frequency invariance

2021-02-28 Thread Viresh Kumar
The Frequency Invariance Engine (FIE) is providing a frequency scaling correction factor that helps achieve more accurate load-tracking. Normally, this scaling factor can be obtained directly with the help of the cpufreq drivers as they know the exact frequency the hardware is running at. But that
