Merge tag 'thermal-v6.9-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux

rafaeljw · rafaeljw · commit 4e7193acdecd · 2024-03-13T20:35:48.000+01:00
Merge additional thermal control changes for 6.9-rc1 from Daniel Lezcano:

"- Fix memory leak in the error path at probe time in the Mediatek LVTS
   driver (Christophe Jaillet)

 - Fix control buffer enablement regression on Meditek MT7896 (Frank
   Wunderlich)

 - Drop spaces before TABs in different places: thermal-of, ST drivers
   and Makefile (Geert Uytterhoeven)

 - Adjust DT binding for NXP as fsl,tmu-range min/maxItems can vary
   among several SoC versions (Fabio Estevam)

 - Add support for H616 THS controller for the Sun8i platforms. Note
   that this change relies on another change in the SoC specific code
   which is included in this branch (Martin Botka)

 - Don't fail probe due to zone registration failure because there is
   no trip points defined in the DT (Mark Brown)

 - Support variable TMU array size for new platforms (Peng Fan)

 - Adjust the DT binding for thermal-of and make the polling time not
   required and assume it is zero when not found in the DT (Konrad
   Dybcio)

 - Add r8a779h0 support in both the DT and the driver (Geert Uytterhoeven)"
