git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux 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.

2016-09-27thermal: Enhance thermal_zone_device_update for eventsSrinivas Pandruvada
Added one additional parameter to thermal_zone_device_update() to provide caller with an optional capability to specify reason. Currently this event is used by user space governor to trigger different processing based on event code. Also it saves an additional call to read temperature when the event is received. The following events are cuurently defined: - Unspecified event - New temperature sample - Trip point violated - Trip point changed - thermal device up and down - thermal device power capability changed Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

2016-09-06thermal: rcar_thermal: Fix priv->zone error handlingDirk Behme
In case thermal_zone_xxx_register() returns an error, priv->zone isn't NULL any more, but contains the error code. This is passed to thermal_zone_device_unregister(), then. This checks for priv->zone being NULL, but the error code is != NULL. So it works with the error code as a pointer. Crashing immediately. To fix this, reset priv->zone to NULL before entering rcar_gen3_thermal_remove().

2015-08-03thermal: consistently use int for temperaturesSascha Hauer
The thermal code uses int, long and unsigned long for temperatures in different places. Using an unsigned type limits the thermal framework to positive temperatures without need. Also several drivers currently will report temperatures near UINT_MAX for temperatures below 0°C. This will probably immediately shut the machine down due to overtemperature if started below 0°C. 'long' is 64bit on several architectures. This is not needed since INT_MAX °mC is above the melting point of all known materials. Consistently use a plain 'int' for temperatures throughout the thermal code and the drivers. This only changes the places in the drivers where the temperature is passed around as pointer, when drivers internally use another type this is not changed.

However, at that point rcar_thermal_common hasn't been initialized complely yet.
