+* Mediatek AUXADC - Analog to Digital Converter on Mediatek mobile soc (mt65xx/mt81xx/mt27xx)
+===============
+
+The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found
+in some Mediatek SoCs which among other things measures the temperatures
+in the SoC. It can be used directly with register accesses, but it is also
+used by thermal controller which reads the temperatures from the AUXADC
+directly via its own bus interface. See
+Documentation/devicetree/bindings/thermal/mediatek-thermal.txt
+for the Thermal Controller which holds a phandle to the AUXADC.
+
+Required properties:
+  - compatible: Should be one of:
+    - "mediatek,mt2701-auxadc": For MT2701 family of SoCs
+    - "mediatek,mt2712-auxadc": For MT2712 family of SoCs
+    - "mediatek,mt6765-auxadc": For MT6765 family of SoCs
+    - "mediatek,mt7622-auxadc": For MT7622 family of SoCs
+    - "mediatek,mt8173-auxadc": For MT8173 family of SoCs
+    - "mediatek,mt8183-auxadc", "mediatek,mt8173-auxadc": For MT8183 family of SoCs
+  - reg: Address range of the AUXADC unit.
+  - clocks: Should contain a clock specifier for each entry in clock-names
+  - clock-names: Should contain "main".
+  - #io-channel-cells: Should be 1, see ../iio-bindings.txt
+
+Example:
+
+auxadc: adc@11001000 {
+	compatible = "mediatek,mt2701-auxadc";
+	reg = <0 0x11001000 0 0x1000>;
+	clocks = <&pericfg CLK_PERI_AUXADC>;
+	clock-names = "main";
+	#io-channel-cells = <1>;
+};
