| * 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>; |
| }; |
