Merge tag 'thermal-v6.6-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux

Merge ARM and related thermal control updates for 6.6-rc1 from Daniel
Lezcano:

"- Check if the Tegra BPMP supports the trip points in order to set the
   .set_trips callback (Mikko Perttunen)

 - Add the new Loongson-2 thermal sensor along with the DT bindings
   (Yinbo Zhu)

 - Use IS_ERR_OR_NULL helper to replace a double test on the TI bandgap
   sensor (Li Zetao)

 - Remove the call to platform_set_drvdata() as there is no call to
   platform_get_drvdata() in a bunch of drivers where that happens
   (Andrei Coardos)

 - Switch the Mediatek LVTS mode to filtered in order to enable the
   interrupts (Nícolas F. R. A. Prado)

 - Fix Wvoid-pointer-to-enum-cast warning on the Exynos TMU (Krzysztof
   Kozlowski)

 - Remove redundant usage of of_match_ptr() as the driver db8500
   already depends on CONFIG_OF (Ruan Jinjie)

 - Remove redundant dev_err_probe() because the underlying function
   already called it in the Mediatek sensor (Chen Jiahao)

 - Free calibration nvmem after reading it on sun8i (Mark Brown)

 - Remove useless comment in the code on sun8i (Yangtao Li)

 - Make tsens_xxxx_nvmem static to fix sparse warning on QCom tsens (Min-Hua Chen)

 - Remove error message at probe deferral on imx8mm (Ahmad Fatoum)

 - Fix parameter check in lvts_debugfs_init with IS_ERR on Mediatek
   LVTS (Minjie Du)

 - Fix the interrupt routine and configuratoin for the Mediatek LVTS
   (Nícolas F. R. A. Prado)"
