* QCOM SoC Temperature Sensor (TSENS)
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible:
|
||
|
|
Must be one of the following:
|
||
|
|
- "qcom,msm8916-tsens" (MSM8916)
|
||
|
|
- "qcom,msm8974-tsens" (MSM8974)
|
||
|
|
- "qcom,msm8996-tsens" (MSM8996)
|
||
|
|
- "qcom,msm8998-tsens", "qcom,tsens-v2" (MSM8998)
|
||
|
|
- "qcom,sdm845-tsens", "qcom,tsens-v2" (SDM845)
|
||
|
|
The generic "qcom,tsens-v2" property must be used as a fallback for any SoC
|
||
|
|
with version 2 of the TSENS IP. MSM8996 is the only exception because the
|
||
|
|
generic property did not exist when support was added.
|
||
|
|
|
||
|
|
- reg: Address range of the thermal registers.
|
||
|
|
New platforms containing v2.x.y of the TSENS IP must specify the SROT and TM
|
||
|
|
register spaces separately, with order being TM before SROT.
|
||
|
|
See Example 2, below.
|
||
|
|
|
||
|
|
- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description.
|
||
|
|
- #qcom,sensors: Number of sensors in tsens block
|
||
|
|
- Refer to Documentation/devicetree/bindings/nvmem/nvmem.txt to know how to specify
|
||
|
|
nvmem cells
|
||
|
|
|
||
|
|
Example 1 (legacy support before a fallback tsens-v2 property was introduced):
|
||
|
|
tsens: thermal-sensor@900000 {
|
||
|
|
compatible = "qcom,msm8916-tsens";
|
||
|
|
reg = <0x4a8000 0x2000>;
|
||
|
|
nvmem-cells = <&tsens_caldata>, <&tsens_calsel>;
|
||
|
|
nvmem-cell-names = "caldata", "calsel";
|
||
|
|
#thermal-sensor-cells = <1>;
|
||
|
|
};
|
||
|
|
|
||
|
|
Example 2 (for any platform containing v2 of the TSENS IP):
|
||
|
|
tsens0: thermal-sensor@c263000 {
|
||
|
|
compatible = "qcom,sdm845-tsens", "qcom,tsens-v2";
|
||
|
|
reg = <0xc263000 0x1ff>, /* TM */
|
||
|
|
<0xc222000 0x1ff>; /* SROT */
|
||
|
|
#qcom,sensors = <13>;
|
||
|
|
#thermal-sensor-cells = <1>;
|
||
|
|
};
