Merge tag 'thermal-v5.17-rc1' of https://git.kernel.org/pub/scm/linux/kernel/git/thermal/linux
Pull thermal control material for 5.17-rc1 from Daniel Lezcano:
- Fix PM issue on the iMX driver when suspend/resume is happening by
implementing PM runtime support (Oleksij Rempel)
- Add 'const' annotation to the thermal_cooling_ops in the Intel
powerclamp driver (Rikard Falkeborn)
- Add TSU driver and bindings for the RZ/G2L platform (Biju Das)
- Fix missing ADC bit set on iMX8MP to enable the sensor (Paul Gerber)
- Fix missing check when calling reset_control_deassert() (Biju Das)
