-* 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,qcs404-tsens", "qcom,tsens-v1" (QCS404)
- - "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.
- Similarly, the generic "qcom,tsens-v1" property must be used as a fallback for
- any SoC with version 1 of the TSENS IP.
-
-- 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>;
- };
-
-Example 3 (for any platform containing v1 of the TSENS IP):
-tsens: thermal-sensor@4a9000 {
- compatible = "qcom,qcs404-tsens", "qcom,tsens-v1";
- reg = <0x004a9000 0x1000>, /* TM */
- <0x004a8000 0x1000>; /* SROT */
- nvmem-cells = <&tsens_caldata>;
- nvmem-cell-names = "calib";
- #qcom,sensors = <10>;
- #thermal-sensor-cells = <1>;
- };

+description: |
+ QCOM SoCs have TSENS IP to allow temperature measurement. There are currently
+ three distinct major versions of the IP that is supported by a single driver.
+ The IP versions are named v0.1, v1 and v2 in the driver, where v0.1 captures
+ everything before v1 when there was no versioning information.
