[PATCH v5 0/1] Add thermal sensors support for MT7981

[PATCH v5 0/1] 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 v5:
 - dropped another accepted patch

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
