3 This describes the device tree binding for the Mediatek thermal controller
4 which measures the on-SoC temperatures. This device does not have its own ADC,
5 instead it directly controls the AUXADC via AHB bus accesses. For this reason
6 this device needs phandles to the AUXADC. Also it controls a mux in the
7 apmixedsys register space via AHB bus accesses, so a phandle to the APMIXEDSYS
12 - "mediatek,mt8173-thermal" : For MT8173 family of SoCs
13 - "mediatek,mt2701-thermal" : For MT2701 family of SoCs
14 - "mediatek,mt2712-thermal" : For MT2712 family of SoCs
15 - "mediatek,mt7622-thermal" : For MT7622 SoC
16 - "mediatek,mt8183-thermal" : For MT8183 family of SoCs
17 - "mediatek,mt8516-thermal", "mediatek,mt2701-thermal : For MT8516 family of SoCs
18 - reg: Address range of the thermal controller
19 - interrupts: IRQ for the thermal controller
20 - clocks, clock-names: Clocks needed for the thermal controller. required
22 "therm": Main clock needed for register access
23 "auxadc": The AUXADC clock
24 - mediatek,auxadc: A phandle to the AUXADC which the thermal controller uses
25 - mediatek,apmixedsys: A phandle to the APMIXEDSYS controller.
26 - #thermal-sensor-cells : Should be 0. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for a description.
29 - resets: Reference to the reset controller controlling the thermal controller.
30 - nvmem-cells: A phandle to the calibration data provided by a nvmem device. If
31 unspecified default values shall be used.
32 - nvmem-cell-names: Should be "calibration-data"
