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"

 - reg:		Device's register space.
 		Two entries are expected, see the examples below.
 		The first one is required for the sensor register;
