Merge tag 'thermal-v7.0' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux

Pull thermal control updates for 6.20/7.0 from Daniel Lezcano:

"- Fix CFLAGS and LDFLAGS in the pkg-config template fir the libthermal
   (Romain Gantois)

 - Support multiple temp to raw conversion functions for the Mediatek
   LVTS thermal driver and add the MT8196 and MT6991 support (Laura
   Nao)

 - Add support for the Mediatek LVTS driver for MT7987 (Frank
   Wunderlich)

 - Use the existing HZ_PER_MHZ macro on STM32 (Andy Shevchenko)

 - Use the existing clamp() macro in BCM2835 (Thorsten Blum)

 - Make the reset line optional in order to support new Renesas Soc
   where it is not available. Add the RZ/T2H and RZ/N2H suppport
   (Cosmin Tanislav)"
