[PATCH v2 1/2] devfreq: qcom: Add L2 Krait Cache devfreq scaling driver

2020-09-29 Thread Ansuel Smith
Qcom L2 Krait CPUs use the generic cpufreq-dt driver and doesn't actually scale the Cache frequency when the CPU frequency is changed. This devfreq driver register with the cpu notifier and scale the Cache based on the max Freq across all core as the CPU cache is shared across all of them. If provi
