* QCOM SoC Temperature Sensor (TSENS)
Required properties:
-- compatible :
- - "qcom,msm8916-tsens" : For 8916 Family of SoCs
- - "qcom,msm8974-tsens" : For 8974 Family of SoCs
- - "qcom,msm8996-tsens" : For 8996 Family of SoCs
+- 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.
-- reg: Address range of the thermal registers
- #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
