+* 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.
+
+Required properties:
+- compatible: "mediatek,mt8173-thermal"
+- 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
+- resets, reset-names: Reference to the reset controller controlling the thermal
+ controller. Required reset-names:
+ "therm": The main reset line
+- auxadc: A phandle to the AUXADC which the thermal controller uses
+- apmixedsys: A phandle to the APMIXEDSYS controller.
+- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description
+
+Example:
+
+ thermal: thermal@1100b000 {
+ #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>;
+ reset-names = "therm";
+ auxadc = <&auxadc>;
+ apmixedsys = <&apmixedsys>;
+ };
