-* Mediatek Thermal
-
-This describes the device tree binding for the Mediatek thermal controller
-which 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:
-- 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
- - "mediatek,mt7986-thermal" : For MT7986 SoC
- - "mediatek,mt8183-thermal" : For MT8183 family of SoCs
- - "mediatek,mt8365-thermal" : For MT8365 family of SoCs
- - "mediatek,mt8516-thermal", "mediatek,mt2701-thermal : For MT8516 family of SoCs
-- 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"
-
-Example:
-
- thermal: thermal@...0b000 {
- #thermal-sensor-cells = <1>;
- compatible = "mediatek,mt8173-thermal";
- reg = <0 0x1100b000 0 0x1000>;
- interrupts = <0 70 IRQ_TYPE_LEVEL_LOW>;
- clocks = <&pericfg CLK_PERI_THERM>, <&pericfg CLK_PERI_AUXADC>;
- clock-names = "therm", "auxadc";
- resets = <&pericfg MT8173_PERI_THERM_SW_RST>;
