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"
