Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal updates from Zhang Rui: - Fix a regression where bogus trip points on some Lenovo laptops start to screw up thermal control after commit 81ad4276b505 ("Thermal: initialize thermal zone device correctly"). On these Lenovo laptops, a bogus passive trip point is reported, which is 0 degree Celsius. Without commit 81ad4276b505, thermal zone fails to set cooling devices to proper cooling state, which is a bug. But with commit 81ad4276b505 applied, the processors are always throttled on these Lenovo laptops because the current temperature is always higher than the passive trip point. Fix things to ignore such bogus trip points. (Zhang Rui) - Introduce Mediatek thermal driver. (Sascha Hauer) - Introduce devm_ versions of OF thermal sensor register API. (Laxman Dewangan) - Changes in Kconfigs to allow compile test on UM arch. (Krzysztof Kozlowski) - Introduce Skylake support in intel_pch_thermal driver. (Srinivas Pandruvada) - Several small fixes on Rockchip, TI-SoC, Tegra, RCar, and Exynos thermal drivers. * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (26 commits) Thermal: Ignore invalid trip points thermal: trace: migrating thermal traces to use TRACE_DEFINE_ENUM() macros thermal: intel_pch_thermal: Enable Skylake PCH thermal thermal: doc: Add details of devm_thermal_zone_of_sensor_{register,unregister} thermal: of-thermal: Add devm version of thermal_zone_of_sensor_register thermal: doc: Add details of thermal_zone_of_sensor_{register,unregister} thermal: exynos: Defer probe if vtmu is present but not registered thermal: exynos: Use devm_regulator_get_optional() for vtmu thermal: exynos: List vtmu-supply as optional property in DT binding thermal: exynos: Print a message about exceeded number of supported trip-points thermal: exynos: Document number of supported trip-points thermal: exynos: Document compatible for Exynos5433 TMU thermal: mtk: allow compile testing on UM thermal: tegra_soctherm: fix sign bit of temperature thermal: Fix build error of missing devm_ioremap_resource on UM thermal: ti-soc-thermal: clean up the error handling a bit thermal: rcar: Use ARCH_RENESAS thermal: rcar_thermal: don't open code of_device_get_match_data() thermal: db8500_cpufreq_cooling: Compile with COMPILE_TEST thermal: rockchip: fix the tsadc sequence output on rk3228/rk3399 ...
