QTI devfreq cooling devices.
The devfreq cooling device will be used by userspace thermal daemon to
vote for frequency cap under thermal conditions. This driver will register a
cooling device for the GPU phandle specified in the devicetree.
Properties:
- compatible:
Usage: required
Value type: <string>
Definition: should be "qcom,devfreq-cdev"
Cooling device node:
- qcom,devfreq:
Usage: required
Value type: <devfreq phandle>
Definition: Phandle to the GPU devfreq. This will register the GPU
devfreq as a cooling device with thermal framework.
Example:
qcom,devfreq-cdev {
compatible = "qcom,devfreq-cdev";
qcom,devfreq = <&msm_gpu>;
};
