QTI LMH CPU Voltage cooling devices.
|
|
|
|
The LMH CPU voltage cooling device will be used to place voltage restriction
|
|
vote on CPU railway during cold thermal condition. This cooling device driver
|
|
will register one cooling device per LLM, which can be used by thermal zone to
|
|
place voltage restriction vote.
|
|
|
|
Properties:
|
|
- compatible:
|
|
Usage: required
|
|
Value type: <string>
|
|
Definition: should be "qcom,lmh-cpu-vdd"
|
|
|
|
Cooling device node:
|
|
- reg:
|
|
Usage: Required
|
|
Value type: <a b>
|
|
Definition: where 'a' is the starting register address of the LLM
|
|
and 'b' is the size of LLM address space.
|
|
|
|
- #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:
|
|
lmh_cpu_vdd0: qcom,lmh-cpu-vdd@18350800 {
|
|
compatible = "qcom,lmh-cpu-vdd";
|
|
reg = <0x18350800 0x1000>;
|
|
#cooling-cells = <2>;
|
|
};
