Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal updates from Zhang Rui:
"Specifics:
- adds full support for 2 types of Thermal Controllers produced by
STMicroelectronics. One is a more traditional memory mapped
variant, the other is controlled solely by system configuration
registers. From Lee Jones.
- add TMU (Thermal Management Unit) support for Exynos3250 Soc.
From Chanwoo Choi.
- add critical and passive trip point support for int3403 thermal
driver. From Srinivas Pandruvada.
- a couple of small fixes/cleanups from Javi Merino, and Geert
Uytterhoeven"
