Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management updates from Zhang Rui:
"There are not too many changes this time, except two new platform
thermal drivers, ti-soc-thermal driver and x86_pkg_temp_thermal
driver, and a couple of small fixes.
Highlights:
- move the ti-soc-thermal driver out of the staging tree to the
thermal tree.
- introduce the x86_pkg_temp_thermal driver. This driver registers
CPU digital temperature package level sensor as a thermal zone.
- small fixes/cleanups including removing redundant use of
platform_set_drvdata() and of_match_ptr for all platform thermal
drivers"
