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>;
|
||
|
|
|
||

|
<...>
|
