+title: Krait Cpu Cache Frequency Scaling dedicated driver
+

+  - Ansuel Smith <ansuelsmth@gmail.com>
+
+description: |
+  This Scale the Krait CPU Cache Frequency and optionally voltage
+  when the Cpu Frequency is changed (using the cpufreq notifier).
+
+  Cache is scaled with the max frequency across all core and the cache
+  frequency will scale based on the configured threshold in the dts.
+
+  The cache thresholds can be set to 3+ frequency bin, idle, nominal and
+  high.
