[PATCH v2] dt-bindings: thermal: idle: Complete the example code

[PATCH v2] dt-bindings: thermal: idle: Complete the example code

[Krzysztof Kozlowski]

Thermal bindings expect the node name with all the zones to be named
'thermal-zones' (hyphen instead of underscore) and thermal zones to end
with '-thermal'.  Also DTS coding style is not to use underscores for
node names.  After using correct names, bindings point warnings for
missing properties, so add also thermal-sensors.  Drop fake top
compatible as it is not useful in this context.

Changes in v2:
1. Drop top level compatible and other properties
2. Add thermal-sensors
3. Rename also trips and cpu-thermal

My bot found errors running 'make dt_binding_check' on your patch:

See https://patchwork.kernel.org/project/devicetree/patch/20260407053957.10508-2-krzysztof.kozlowski@oss.qualcomm.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

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 after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
