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.

Not tested. You miss constraints. Drop totally redundant description.

-Required properties:
-- compatible:
- - "mediatek,mt8173-thermal" : For MT8173 family of SoCs
- - "mediatek,mt2701-thermal" : For MT2701 family of SoCs
- - "mediatek,mt2712-thermal" : For MT2712 family of SoCs
- - "mediatek,mt7622-thermal" : For MT7622 SoC
- - "mediatek,mt7981-thermal", "mediatek,mt7986-thermal" : For MT7981 SoC

-- reg: Address range of the thermal controller
-- interrupts: IRQ for the thermal controller
-- clocks, clock-names: Clocks needed for the thermal controller. required
- clocks are:
- "therm": Main clock needed for register access
- "auxadc": The AUXADC clock
-- mediatek,auxadc: A phandle to the AUXADC which the thermal controller uses
-- mediatek,apmixedsys: A phandle to the APMIXEDSYS controller.
-- #thermal-sensor-cells : Should be 0. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for a description.
-
-Optional properties:
-- resets: Reference to the reset controller controlling the thermal controller.
-- nvmem-cells: A phandle to the calibration data provided by a nvmem device. If
- unspecified default values shall be used.
-- nvmem-cell-names: Should be "calibration-data"
