Merge tag 'thermal-v6.8-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux into thermal

Merge thermal control material for 6.8-rc1 from Daniel Lezcano:

"- Converted Mediatek Thermal to the json-schema (Rafał Miłecki)

 - Fixed DT bindings issue on Loongson (Binbin Zhou)

 - Fixed returning NULL instead of -ENODEV on Loogsoo (Binbin Zhou)

 - Added the DT binding for the tsens on SM8650 platform (Neil Armstrong)

 - Added a reboot on critical option feature (Fabio Estevam)

 - Made usage of DEFINE_SIMPLE_DEV_PM_OPS on AmLogic (Uwe Kleine-König)

 - Added the D1/T113s THS controller support on Sun8i (Maxim Kiselev)

 - Fixed example in the DT binding for QCom SPMI (Johan Hovold)

 - Fixed compilation warning for the tmon utility (Florian Eckert)

 - Added interrupt based configuration on Exynos along with a set of
   related cleanups (Mateusz Majewski)"
