since mt8192 only has one of them.

Ditto.

Then add allOf:if:then: which will constrain it per variant/compatible.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Error: Documentation/devicetree/bindings/thermal/mediatek,lvts-thermal.example.dts:32.36-37 syntax error
FATAL ERROR: Unable to parse input tree
make[1]: *** [scripts/Makefile.lib:383: Documentation/devicetree/bindings/thermal/mediatek,lvts-thermal.example.dtb] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [Makefile:1404: dt_binding_check] Error 2

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

Do not use "This commit/patch".

Please rebase your patches on recent Linux kernel (or next).

Any reason why not referencing thermal-sensor.yaml?

You need to describe the items (like nvmem-cells).

Mixed-up indentation.
