* QCOM SoC Temperature Sensor (TSENS)
Required properties:

+ 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.
