Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal

Pull thermal management updates from Eduardo Valentin:

 - rework tsens driver to add support for tsens-v2 (Amit Kucheria)

 - rework armada thermal driver to use syscon and multichannel support
   (Miquel Raynal)

 - fixes to TI SoC, IMX, Exynos, RCar, and hwmon drivers

 * QCOM SoC Temperature Sensor (TSENS)
 
 Required properties:

- - "qcom,msm8916-tsens" : For 8916 Family of SoCs
- - "qcom,msm8974-tsens" : For 8974 Family of SoCs
- - "qcom,msm8996-tsens" : For 8996 Family of SoCs

+  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
