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

Pull thermal management update from Zhang Rui:
 "Summary:

   - of-thermal extension to allow drivers to register and use its
     functionality in a better way, without exploiting thermal core.
     From Lukasz Majewski.

   - Fix a bug in intel_soc_dts_thermal driver which calls a sleep
     function in interrupt handler.  From Maurice Petallo.

   - add a thermal UAPI header file for exporting the thermal generic
     netlink information to user-space.  From Florian Fainelli.

   - First round of refactoring in Exynos driver.  Bartlomiej and Lukasz
     are attempting to make it lean and easier to understand.

   - New thermal driver for Rockchip (rk3288), with support for DT
     thermal.  From Caesar Wang.

   - New thermal driver for Nvidia, Tegra124 SOCTHERM driver, with
     support for DT thermal.  From Mikko Perttunen.

   - New cooling device, based on common clock framework.  From Eduardo
     Valentin.

   - a couple of small fixes in thermal core framework.  From Srinivas
     Pandruvada, Javi Merino, Luis Henriques.

   - Dropping Armada A375-Z1 SoC thermal support as the chip is not in
     the market, armada folks decided to drop its support.

   - a couple of small fixes and cleanups in int340x thermal driver"

+Tegra124 SOCTHERM thermal management system
+
+The SOCTHERM IP block contains thermal sensors, support for polled

+on temperature trip points, and handling external overcurrent
+notifications. It is also used to manage emergency shutdown in an
+overheating situation.
+
+Required properties :
+- compatible : "nvidia,tegra124-soctherm".
+- reg : Should contain 1 entry:
+  - SOCTHERM register set
+- interrupts : Defines the interrupt used by SOCTHERM
+- clocks : Must contain an entry for each entry in clock-names.
+  See ../clocks/clock-bindings.txt for details.
+- clock-names : Must include the following entries:
+  - tsensor
+  - soctherm
+- resets : Must contain an entry for each entry in reset-names.
+  See ../reset/reset.txt for details.
+- reset-names : Must include the following entries:
+  - soctherm
+- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description
