Kernel-4.18.0-80.el8_cpufreq-exynos5440

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>;
};
