+description: |
+  The MediaTek thermal controller measures the on-SoC temperatures.
+  This device does not have its own ADC, instead it directly controls
+  the AUXADC via AHB bus accesses. For this reason this device needs
+  phandles to the AUXADC. Also it controls a mux in the apmixedsys
+  register space via AHB bus accesses, so a phandle to the APMIXEDSYS
+  is also needed.

-Required properties:

-  - "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

-- 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"
