QTI CPU hotplug cooling devices.
|
|
|
|
The CPU hotplug cooling device will be used for hotpluging a CPU on a thermal
|
|
condition. This cooling device driver can register one cooling device per CPU,
|
|
which can be used by thermal zone to mitigate.
|
|
|
|
Each child node will represent a cooling device and the child node should
|
|
point to the CPU, which will be mitigated by that cooling device instance.
|
|
|
|
Properties:
|
|
- compatible:
|
|
Usage: required
|
|
Value type: <string>
|
|
Definition: should be "qcom,cpu-hotplug"
|
|
|
|
Cooling device node:
|
|
- qcom,cpu:
|
|
Usage: required
|
|
Value type: <phandle>
|
|
Definition: phandle to the CPU device that this cooling device will
|
|
mitigate.
|
|
|
|
-#cooling-cells:
|
|
Usage: required
|
|
Value type: <integer>
|
|
Definition: Must be 2. Needed for of_thermal as cooling device
|
|
identifier. Please refer to
|
|
<devicetree/bindings/thermal/thermal.txt> for more
|
|
details.
|
|
Example:
|
|
qcom,cpu-hotplug {
|
|
compatible = "qcom,cpu-hotplug";
|
|
|
|
cpu0_hotplug: cpu0-hotplug {
|
|
qcom,cpu = <&CPU0>;
|
|
#cooling-cells = <2>;
|
|
};
|
|
cpu1_hotplug: cpu1-hotplug {
|
|
qcom,cpu = <&CPU1>;
|
|
#cooling-cells = <2>;
|
|
};
|
|
cpu2_hotplug: cpu2-hotplug {
|
|
qcom,cpu = <&CPU2>;
|
|
#cooling-cells = <2>;
|
|
};
|
|
cpu3_hotplug: cpu3-hotplug {
|
|
qcom,cpu = <&CPU3>;
|
|
#cooling-cells = <2>;
|
|
};
|
|
};
