Kernel-3.10.0-957.el7_cpufreq-spear

SPEAr cpufreq driver

SPEAr SoC cpufreq driver for CPU frequency scaling.
It supports both uniprocessor (UP) and symmetric multiprocessor (SMP) systems
which share clock across all CPUs.

Required properties:

• cpufreq_tbl: Table of frequencies CPU could be transitioned into, in the
  increasing order.

Optional properties:

• clock-latency: Specify the possible maximum transition latency for clock, in
  unit of nanoseconds.

Both required and optional properties listed above must be defined under node
/cpus/cpu@0.

Examples:

cpus {

<...>

cpu@0 {
    compatible = "arm,cortex-a9";
    reg = <0>;

    <...>

    cpufreq_tbl = < 166000
            200000
            250000
            300000
            400000
            500000
            600000 >;
};
