Exynos5440 cpufreq driver
Exynos5440 SoC cpufreq driver for CPU frequency scaling.
Required properties:
- interrupts: Interrupt to know the completion of cpu frequency change.
- operating-points: Table of frequencies and voltage CPU could be transitioned into,
in the decreasing order. Frequency should be in KHz units and voltage
should be in microvolts.
Optional properties:
- clock-latency: Clock monitor latency in microsecond.
All the required listed above must be defined under node cpufreq.
