Merge tag 'thermal-v7.1-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux

Merge updates of assorted thermal drivers for 7.1-rc1 from Daniel
Lezcano:

"- Added an OF node address to output message to make sensor names more
   distinguishable (Alexander Stein)

 - Added hwmon support for the i.MX97 thermal sensor (Alexander Stein)

 - Clamped correctly the results when doing value/temperature conversion
   in the Spreadtrum driver (Thorsten Blum)

 - Added the SDM670 compatible DT bindings for the Tsens and the lMH
   drivers (Richard Acayan)

 - Added the SM8750 compatible DT bindings for the Tsens (Manaf
   Meethalavalappu Pallikunhi)

 - Added the Eliza SoC compatible DT bindings for the Tsens (Krzysztof
   Kozlowski)

 - Fixed inverted condition check on error in the Spear driver (Gopi
   Krishna Menon)

 - Converted the DT bindings documentation into DT schema (Gopi Krishna
   Menon)

 - Used max() macro to increase readibility in the Broadcom STB thermal
   sensor (Thorsten Blum)

 - Removed stale @trim_offset kernel-doc entry (John Madieu)"
