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>;
	};
