Merge tag 'thermal-v5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thermal/linux
Pull thermal updates from Daniel Lezcano: - Add the hwmon support on the i.MX SC (Anson Huang) - Thermal framework cleanups (self-encapsulation, pointless stubs, private structures) (Daniel Lezcano) - Use the PM QoS frequency changes for the devfreq cooling device (Matthias Kaehlcke) - Remove duplicate error messages from platform_get_irq() error handling (Markus Elfring) - Add support for the bandgap sensors (Keerthy) - Statically initialize .get_mode/.set_mode ops (Andrzej Pietrasiewicz) - Add Renesas R-Car maintainer entry (Niklas Söderlund) - Fix error checking after calling ti_bandgap_get_sensor_data() for the TI SoC thermal (Sudip Mukherjee) - Add latency constraint for the idle injection, the DT binding and the change the registering function (Daniel Lezcano) - Convert the thermal framework binding to the Yaml schema (Amit Kucheria) - Replace zero-length array with flexible-array on i.MX 8MM (Gustavo A. R. Silva) - Thermal framework cleanups (alphabetic order for heads, replace module.h by export.h, make file naming consistent) (Amit Kucheria) - Merge tsens-common into the tsens driver (Amit Kucheria) - Fix platform dependency for the Qoriq driver (Geert Uytterhoeven) - Clean up the rcar_thermal_update_temp() function in the rcar thermal driver (Niklas Söderlund) - Fix the TMSAR register for the TMUv2 on the Qoriq platform (Yuantian Tang) - Export GDDV, OEM vendor variables, and don't require IDSP for the int340x thermal driver - trivial conflicts fixed (Matthew Garrett) * tag 'thermal-v5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thermal/linux: (48 commits) thermal/int340x_thermal: Don't require IDSP to exist thermal/int340x_thermal: Export OEM vendor variables thermal/int340x_thermal: Export GDDV thermal: qoriq: Update the settings for TMUv2 thermal: rcar_thermal: Clean up rcar_thermal_update_temp() thermal: qoriq: Add platform dependencies drivers: thermal: tsens: Merge tsens-common.c into tsens.c thermal/of: Rename of-thermal.c thermal/governors: Prefix all source files with gov_ thermal/drivers/user_space: Sort headers alphabetically thermal/drivers/of-thermal: Sort headers alphabetically thermal/drivers/cpufreq_cooling: Replace module.h with export.h thermal/drivers/cpufreq_cooling: Sort headers alphabetically thermal/drivers/clock_cooling: Include export.h thermal/drivers/clock_cooling: Sort headers alphabetically thermal/drivers/thermal_hwmon: Include export.h thermal/drivers/thermal_hwmon: Sort headers alphabetically thermal/drivers/thermal_helpers: Include export.h thermal/drivers/thermal_helpers: Sort headers alphabetically thermal/core: Replace module.h with export.h ...
