Merge tag 'thermal-v5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thermal/linux
Pull thermal updates from Daniel Lezcano: - Use the newly introduced 'hot' and 'critical' ops for the acpi thermal driver (Daniel Lezcano) - Remove the notify ops as it is no longer used (Daniel Lezcano) - Remove the 'forced passive' option and the unused bind/unbind functions (Daniel Lezcano) - Remove the THERMAL_TRIPS_NONE and the code cleanup around this macro (Daniel Lezcano) - Rework the delays to make them pre-computed instead of computing them again and again at each polling interval (Daniel Lezcano) - Remove the pointless 'thermal_zone_device_reset' function (Daniel Lezcano) - Use the critical and hot ops to prevent an unexpected system shutdown on int340x (Kai-Heng Feng) - Make the cooling device state private to the thermal subsystem (Daniel Lezcano) - Prevent to use not-power-aware actor devices with the power allocator governor (Lukasz Luba) - Remove 'zx' and 'tango' support along with the corresponding platforms (Arnd Bergman) - Fix several issues on the Omap thermal driver (Tony Lindgren) - Add support for adc-tm5 PMIC thermal monitor for Qcom platforms (Dmitry Baryshkov) - Fix an initialization loop in the adc-tm5 (Colin Ian King) - Fix a return error check in the cpufreq cooling device (Viresh Kumar) * tag 'thermal-v5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thermal/linux: (26 commits) thermal: cpufreq_cooling: freq_qos_update_request() returns < 0 on error thermal: qcom: Fix comparison with uninitialized variable channels_available thermal: qcom: add support for adc-tm5 PMIC thermal monitor dt-bindings: thermal: qcom: add adc-thermal monitor bindings thermal: ti-soc-thermal: Use non-inverted define for omap4 thermal: ti-soc-thermal: Simplify polling with iopoll thermal: ti-soc-thermal: Fix stuck sensor with continuous mode for 4430 thermal: ti-soc-thermal: Skip pointless register access for dra7 thermal/drivers/zx: Remove zx driver thermal/drivers/tango: Remove tango driver thermal: power allocator: fail binding for non-power actor devices thermal/core: Make cooling device state change private thermal: intel: pch: Fix unexpected shutdown at critical temperature thermal: int340x: Fix unexpected shutdown at critical temperature thermal/core: Remove pointless thermal_zone_device_reset() function thermal/core: Remove ms based delay fields thermal/core: Use precomputed jiffies for the polling thermal/core: Precompute the delays from msecs to jiffies thermal/core: Remove unused macro THERMAL_TRIPS_NONE thermal/core: Remove THERMAL_TRIPS_NONE test ...
