|
|
- reg: shall contain base register location and length.
|
|
- reg-names: shall contain the frequency domain name.

|
|
|
Optional Properties:
|
|
- qcom,freq-hw-domain: phandle to the frequency domain device node.
|
|
|
|
Usage :
|
|
The following debug node would get created under qcom-cpufreq-hw directory.
|
|

cpufreq_hw_debug: qcom,cpufreq-hw-debug@18591000 {
|
|
compatible = "qcom,cpufreq-hw-debug";
|
|
reg = <0x18591000 0x800>;
|
|
reg-names = "domain-top";
|
|
qcom,freq-hw-domain = <&cpufreq_hw 0>, <&cpufreq_hw 1>,
|
|
<&cpufreq_hw 2>;
|
