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>;
|
|
};
