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

Pull thermal management update from Zhang Rui:
 "Specifics:

   - fix a bug in Exynos thermal driver, which overwrites the hardware
     trip point threshold when updating software trigger levels and
     results in emergency shutdown.  From: Tushar Behera.

   - add thermal sensor support for Armada 375 and 38x SoCs.  From
     Ezequiel Garcia.

   - add TMU (Thermal Management Unit) support for Exynos5260 and
     Exynos5420 SoCs.  From Naveen Krishna Chatradhi.

   - add support for the additional digital temperature sensors in the
     Intel SoCs like Bay Trail.  From: Srinivas Pandruvada.

   - a couple of cleanups and small fixes from Jingoo Han, Bartlomiej
     Zolnierkiewicz, Geert Uytterhoeven, Jacob Pan, Paul Walmsley and
     Lan,Tianyu"

* Marvell Armada 370/XP thermal management
* Marvell Armada 370/375/380/XP thermal management
Required properties:
- compatible: Should be set to one of the following:
marvell,armada370-thermal
marvell,armada375-thermal
marvell,armada375-z1-thermal
marvell,armada380-thermal
marvell,armadaxp-thermal
Note: As the name suggests, "marvell,armada375-z1-thermal"
applies for the SoC Z1 stepping only. On such stepping
some quirks need to be done and the register offset differs
from the one in the A0 stepping.
The operating system may auto-detect the SoC stepping and
update the compatible and register offsets at runtime.
- reg: Device's register space.
Two entries are expected, see the examples below.
The first one is required for the sensor register;

Enable this to register Intel SoCs (e.g. Bay Trail) platform digital
temperature sensor (DTS). These SoCs have two additional DTSs in
addition to DTSs on CPU cores. Each DTS will be registered as a
thermal zone. There are two trip points. One of the trip point can
be set by user mode programs to get notifications via Linux thermal
notification methods.The other trip is a critical trip point, which
was set by the driver based on the TJ MAX temperature.
