+* 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,mt8173-auxadc": For MT8173 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>;

+ - vref-n-supply: The regulator supply for negative analog voltage reference
+ (Note that this must not go below GND or exceed vref-p)
+ If not specified, this is assumed to be analog ground.
+ - ti,acquisition-time: The number of conversion clock periods for the S/H's
