Merge tag 'thermal-6.6-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more thermal control updates from Rafael Wysocki: "These are mostly updates of thermal control drivers for ARM platforms, new thermal control support for Loongson-2 and a couple of core cleanups made possible by recent changes merged previously. Specifics: - Check if the Tegra BPMP supports the trip points in order to set the .set_trips callback (Mikko Perttunen) - Add 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 redundant platform_set_drvdata() calls, as there are no corresponding calls to platform_get_drvdata(), from a bunch of drivers (Andrei Coardos) - Switch the Mediatek LVTS mode to filtered in order to enable interrupts (NĂ­colas F. R. A. Prado) - Fix Wvoid-pointer-to-enum-cast warning on the Exynos TMU (Krzysztof Kozlowski) - Remove redundant dev_err_probe(), because the underlying function already called it, from the Mediatek sensor (Chen Jiahao) - Free calibration nvmem after reading it on sun8i (Mark Brown) - Remove useless comment from the sun8i driver (Yangtao Li) - Make tsens_xxxx_nvmem static to fix a 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 interrupt routine and configuratoin for Mediatek LVTS (NĂ­colas F. R. A. Prado) - Drop unused .get_trip_type(), .get_trip_temp() and .get_trip_hyst() thermal zone callbacks from the core and rework the .get_trend() one to take a trip point pointer as an argument (Rafael Wysocki)" * tag 'thermal-6.6-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (29 commits) thermal: core: Rework .get_trend() thermal zone callback thermal: core: Drop unused .get_trip_*() callbacks thermal/drivers/tegra-bpmp: Check if BPMP supports trip points thermal: dt-bindings: add loongson-2 thermal thermal/drivers/loongson-2: Add thermal management support thermal/drivers/ti-soc-thermal: Use helper function IS_ERR_OR_NULL() thermal/drivers/generic-adc: Removed unneeded call to platform_set_drvdata() thermal/drivers/max77620_thermal: Removed unneeded call to platform_set_drvdata() thermal/drivers/mediatek/auxadc_thermal: Removed call to platform_set_drvdata() thermal/drivers/sun8i_thermal: Remove unneeded call to platform_set_drvdata() thermal/drivers/broadcom/brcstb_thermal: Removed unneeded platform_set_drvdata() thermal/drivers/mediatek/lvts_thermal: Make readings valid in filtered mode thermal/drivers/k3_bandgap: Remove unneeded call to platform_set_drvdata() thermal/drivers/k3_j72xx_bandgap: Removed unneeded call to platform_set_drvdata() thermal/drivers/broadcom/sr-thermal: Removed call to platform_set_drvdata() thermal/drivers/samsung: Fix Wvoid-pointer-to-enum-cast warning thermal/drivers/db8500: Remove redundant of_match_ptr() thermal/drivers/mediatek: Clean up redundant dev_err_probe() thermal/drivers/sun8i: Free calibration nvmem after reading it thermal/drivers/sun8i: Remove unneeded comments ...
