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"

+	  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.
