Qualcomm MSM CPUfreq device
|
||
|
|
|
||
|
|
msm-cpufreq is a device that represents the list of usable CPU frequencies
|
||
|
|
and provides a device handle for the CPUfreq driver to get the CPU and cache
|
||
|
|
clocks.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Must be "qcom,msm-cpufreq"
|
||
|
|
- qcom,cpufreq-table, or qcom,cpufreq-table-<X>:
|
||
|
|
A list of usable CPU frequencies (KHz).
|
||
|
|
Use "qcom,cpufreq-table" if all CPUs in the system
|
||
|
|
should share same list of frequencies.
|
||
|
|
Use "qcom,cpufreq-table-<cpuid>" to describe
|
||
|
|
different CPU freq tables for different CPUs.
|
||
|
|
The table should be listed only for the first CPU
|
||
|
|
if multiple CPUs are synchronous.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- clock-names: When DT based binding of clock is available, this
|
||
|
|
provides a list of CPU subsystem clocks.
|
||
|
|
"cpuX_clk" for every CPU that's present.
|
||
|
|
"l2_clk" when an async cache/CCI is present.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- qcom,governor-per-policy: This property denotes that governor tunables
|
||
|
|
should be associated with each cpufreq policy
|
||
|
|
group instead of being global.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
qcom,msm-cpufreq@0 {
|
||
|
|
regs = <0 4>
|
||
|
|
compatible = "qcom,msm-cpufreq";
|
||
|
|
qcom,cpufreq-table =
|
||
|
|
< 300000 >,
|
||
|
|
< 422400 >,
|
||
|
|
< 652800 >,
