Pull thermal managament updates from Zhang Rui:

 - Enhance thermal "userspace" governor to export the reason when a
   thermal event is triggered and delivered to user space. From Srinivas
   Pandruvada

 - Introduce a single TSENS thermal driver for the different versions of
   the TSENS IP that exist, on different qcom msm/apq SoCs'. Support for
   msm8916, msm8960, msm8974 and msm8996 families is also added. From
   Rajendra Nayak

 - Introduce hardware-tracked trip points support to the device tree
   thermal sensor framework. The framework supports an arbitrary number
   of trip points. Whenever the current temperature is changed, the trip
   points immediately below and above the current temperature are found,
   driver callback is invoked to program the hardware to get notified
   when either of the two trip points are triggered. Hardware-tracked
   trip points support for rockchip thermal driver is also added at the
   same time. From Sascha Hauer, Caesar Wang

 - Introduce a new thermal driver, which enables TMU (Thermal Monitor
   Unit) on QorIQ platform. From Jia Hongtao

 - Introduce a new thermal driver for Maxim MAX77620. From Laxman
   Dewangan

 - Introduce a new thermal driver for Intel platforms using WhiskeyCove
   PMIC. From Bin Gao

 - Add mt2701 chip support to MTK thermal driver. From Dawei Chien

 - Enhance Tegra thermal driver to enable soctherm node and set
   "critical", "hot" trips, for Tegra124, Tegra132, Tegra210. From Wei
   Ni

 - Add resume support for tango thermal driver. From Marc Gonzalez

 - several small fixes and improvements for rockchip, qcom, imx, rcar,
   mtk thermal drivers and thermal core code. From Caesar Wang, Keerthy,
   Rocky Hao, Wei Yongjun, Peter Robinson, Bui Duc Phuc, Axel Lin, Hugh
   Kang

+Thermal driver for MAX77620 Power management IC from Maxim Semiconductor.
+
+Maxim Semiconductor MAX77620 supports alarm interrupts when its
+die temperature crosses 120C and 140C. These threshold temperatures
+are not configurable. Device does not provide the real temperature
+of die other than just indicating whether temperature is above or
+below threshold level.
