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 >;
};
<...>
};
