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.
Example:
--------
cpufreq@160000 {
compatible = "samsung,exynos5440-cpufreq";
reg = <0x160000 0x1000>;
interrupts = <0 57 0>;
operating-points = <
1000000 975000
800000 925000>;
clock-latency = <100000>;
};
