- 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>;
- };
