Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management updates from Zhang Rui:
- Introduce generic ADC thermal driver, based on OF thermal (Laxman
Dewangan)
- Introduce new thermal driver for Tango chips (Marc Gonzalez)
- Rockchip driver support for RK3399, RK3366, and some fixes (Caesar
Wang, Elaine Zhang and Shawn Lin)
- Add CPU power cooling model to Mediatek thermal driver (Dawei Chien)
- Wider usage of dev_thermal_zone_of_sensor_register (Eduardo Valentin)
- TI thermal driver gained a new maintainer (Keerthy).
- Enabled powerclamp driver by checking CPU feature and package cstate
counter instead of CPU whitelist (Jacob Pan)
- Various fixes on thermal governor, OF thermal, Tegra, and RCAR
