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 * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (50 commits) thermal: tango: initialize TEMPSI_CFG thermal: rockchip: use the usleep_range instead of udelay thermal: rockchip: add the notes for better reading thermal: rockchip: Support RK3366 SoCs in the thermal driver thermal: rockchip: handle the power sequence for tsadc controller thermal: rockchip: update the tsadc table for rk3399 thermal: rockchip: fixes the code_to_temp for tsadc driver thermal: rockchip: disable thermal->clk in err case thermal: tegra: add Tegra132 specific SOC_THERM driver thermal: fix ptr_ret.cocci warnings thermal: mediatek: Add cpu dynamic power cooling model. thermal: generic-adc: Add ADC based thermal sensor driver thermal: generic-adc: Add DT binding for ADC based thermal sensor thermal: tegra: fix static checker warning thermal: tegra: mark PM functions __maybe_unused thermal: add temperature sensor support for tango SoC thermal: hisilicon: fix IRQ imbalance enabling thermal: hisilicon: support to use any sensor thermal: rcar: Remove binding docs for r8a7794 thermal: tegra: add PM support ...
