[PATCH v4 0/2] Add thermal sensors support for MT7981

[PATCH v4 0/2] Add thermal sensors support for MT7981

[Aleksander Jan Bajkowski]

This patch adds support for the temperature sensor in the MT7981 SoC.
This sensor is exactly the same as the one in the MT7986.

Changes in v4:
 - sorted bindings by fallback names
 - dropped accepted patch

Changes in v3:
 - added fallback in bindings

Changes in v2:
 - added fallback to an existing compatible string
 - removed second patch as obsolete

Aleksander Jan Bajkowski (2):
  dt-bindings: thermal: mediatek: add falback compatible string for
    MT7981 and MT8516
  arm64: dts: mediatek: add thermal sensor support on mt7981

[PATCH v4 1/2] dt-bindings: thermal: mediatek: add falback compatible string for MT7981 and MT8516

[Aleksander Jan Bajkowski]

The ‘mediatek,mt7981-thermal’ and ‘mediatek,mt8516-thermal’ strings
aren't definied in the driver. Both should have fallback compatible
strings. This commit fixes this issue.

I see my mistake I did while converting to JSON schema. Thanks for 
sorting it out.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/v6.16-rc1-8-g95a042a0c8ec (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

Hi,

this is a false positive. The binding patch [1] is already queued for 
6.17 :)
