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)
