Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux

Pull thermal updates from Zhang Rui:

 - Fix a regression where bogus trip points on some Lenovo laptops start
   to screw up thermal control after commit 81ad4276b505 ("Thermal:
   initialize thermal zone device correctly").

   On these Lenovo laptops, a bogus passive trip point is reported,
   which is 0 degree Celsius.  Without commit 81ad4276b505, thermal zone
   fails to set cooling devices to proper cooling state, which is a bug.
   But with commit 81ad4276b505 applied, the processors are always
   throttled on these Lenovo laptops because the current temperature is
   always higher than the passive trip point.

   Fix things to ignore such bogus trip points.  (Zhang Rui)

 - Introduce Mediatek thermal driver.  (Sascha Hauer)

 - Introduce devm_ versions of OF thermal sensor register API.  (Laxman
   Dewangan)

 - Changes in Kconfigs to allow compile test on UM arch.  (Krzysztof
   Kozlowski)

 - Introduce Skylake support in intel_pch_thermal driver.  (Srinivas
   Pandruvada)

 - Several small fixes on Rockchip, TI-SoC, Tegra, RCar, and Exynos
   thermal drivers.

+* Mediatek Thermal
+
+This describes the device tree binding for the Mediatek thermal controller
+which measures the on-SoC temperatures. This device does not have its own ADC,
+instead it directly controls the AUXADC via AHB bus accesses. For this reason
+this device needs phandles to the AUXADC. Also it controls a mux in the
+apmixedsys register space via AHB bus accesses, so a phandle to the APMIXEDSYS
+is also needed.
+
+Required properties:
+- compatible: "mediatek,mt8173-thermal"
+- reg: Address range of the thermal controller
+- interrupts: IRQ for the thermal controller
+- clocks, clock-names: Clocks needed for the thermal controller. required
+                       clocks are:
+		       "therm":	 Main clock needed for register access
+		       "auxadc": The AUXADC clock
+- resets: Reference to the reset controller controlling the thermal controller.
+- mediatek,auxadc: A phandle to the AUXADC which the thermal controller uses
+- mediatek,apmixedsys: A phandle to the APMIXEDSYS controller.
+- #thermal-sensor-cells : Should be 0. See ./thermal.txt for a description.
+
+Optional properties:
+- nvmem-cells: A phandle to the calibration data provided by a nvmem device. If
+               unspecified default values shall be used.
+- nvmem-cell-names: Should be "calibration-data"
+
+Example:
+
+	thermal: thermal@1100b000 {
+		#thermal-sensor-cells = <1>;
+		compatible = "mediatek,mt8173-thermal";
+		reg = <0 0x1100b000 0 0x1000>;
+		interrupts = <0 70 IRQ_TYPE_LEVEL_LOW>;
+		clocks = <&pericfg CLK_PERI_THERM>, <&pericfg CLK_PERI_AUXADC>;
+		clock-names = "therm", "auxadc";
+		resets = <&pericfg MT8173_PERI_THERM_SW_RST>;
+		reset-names = "therm";
+		mediatek,auxadc = <&auxadc>;

+		struct device *dev, int sensor_id, void *data,
+		const struct thermal_zone_of_device_ops *ops)
+
+	This interface adds a new sensor to a DT thermal zone.
+	This function will search the list of thermal zones described in
+	device tree and look for the zone that refer to the sensor device
+	pointed by dev->of_node as temperature providers. For the zone
+	pointing to the sensor node, the sensor will be added to the DT
+	thermal zone device.
+
+	The parameters for this interface are:
+	dev:		Device node of sensor containing valid node pointer in
+			dev->of_node.
+	sensor_id:	a sensor identifier, in case the sensor IP has more
+			than one sensors
+	data:		a private pointer (owned by the caller) that will be
+			passed back, when a temperature reading is needed.
+	ops:		struct thermal_zone_of_device_ops *.
+
+			get_temp:	a pointer to a function that reads the
+					sensor temperature. This is mandatory
+					callback provided by sensor driver.
+			get_trend: 	a pointer to a function that reads the
+					sensor temperature trend.
+			set_emul_temp:	a pointer to a function that sets
+					sensor emulated temperature.
+	The thermal zone temperature is provided by the get_temp() function
+	pointer of thermal_zone_of_device_ops. When called, it will
+	have the private pointer @data back.
+
+	It returns error pointer if fails otherwise valid thermal zone device
+	handle. Caller should check the return handle with IS_ERR() for finding
+	whether success or not.
+
+1.1.4 void thermal_zone_of_sensor_unregister(struct device *dev,
+		struct thermal_zone_device *tzd)
+
+	This interface unregisters a sensor from a DT thermal zone which was
+	successfully added by interface thermal_zone_of_sensor_register().
+	This function removes the sensor callbacks and private data from the
+	thermal zone device registered with thermal_zone_of_sensor_register()
+	interface. It will also silent the zone by remove the .get_temp() and
+	get_trend() thermal zone device callbacks.

+		struct device *dev, int sensor_id,

+
+	This interface is resource managed version of
+	thermal_zone_of_sensor_register().
+	All details of thermal_zone_of_sensor_register() described in
+	section 1.1.3 is applicable here.
+	The benefit of using this interface to register sensor is that it
+	is not require to explicitly call thermal_zone_of_sensor_unregister()
+	in error path or during driver unbinding as this is done by driver
+	resource manager.
