+Analog Devices AD7124 ADC device driver
+
+Required properties for the AD7124:
+	- compatible: Must be one of "adi,ad7124-4" or "adi,ad7124-8"
+	- reg: SPI chip select number for the device
+	- spi-max-frequency: Max SPI frequency to use
+		see: Documentation/devicetree/bindings/spi/spi-bus.txt
+	- clocks: phandle to the master clock (mclk)
+		see: Documentation/devicetree/bindings/clock/clock-bindings.txt
+	- clock-names: Must be "mclk".
+	- interrupts: IRQ line for the ADC
+		see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+
+	  Required properties:
+		* #address-cells: Must be 1.
+		* #size-cells: Must be 0.
+
+	  Subnode(s) represent the external channels which are connected to the ADC.
+	  Each subnode represents one channel and has the following properties:
+		Required properties:
+			* reg: The channel number. It can have up to 4 channels on ad7124-4
+			  and 8 channels on ad7124-8, numbered from 0 to 15.
+			* diff-channels: see: Documentation/devicetree/bindings/iio/adc/adc.txt
+
+		Optional properties:
+			* bipolar: see: Documentation/devicetree/bindings/iio/adc/adc.txt
+			* adi,reference-select: Select the reference source to use when
+			  converting on the the specific channel. Valid values are:
+			  0: REFIN1(+)/REFIN1(−).
+			  1: REFIN2(+)/REFIN2(−).
+			  3: AVDD
+			  If this field is left empty, internal reference is selected.
+
+Optional properties:
+	- refin1-supply: refin1 supply can be used as reference for conversion.
+	- refin2-supply: refin2 supply can be used as reference for conversion.
+	- avdd-supply: avdd supply can be used as reference for conversion.
+
+Example:
+	adc@0 {
+		compatible = "adi,ad7124-4";
+		reg = <0>;
+		spi-max-frequency = <5000000>;
+		interrupts = <25 2>;
+		interrupt-parent = <&gpio>;
+		refin1-supply = <&adc_vref>;
+		clocks = <&ad7124_mclk>;
+		clock-names = "mclk";
+
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		channel@0 {
+			reg = <0>;
+			diff-channels = <0 1>;
+			adi,reference-select = <0>;
+		};
+
+		channel@1 {
+			reg = <1>;
+			bipolar;
+			diff-channels = <2 3>;
+			adi,reference-select = <0>;
+		};
+
+		channel@2 {
+			reg = <2>;
+			diff-channels = <4 5>;
+		};
+
+		channel@3 {
+			reg = <3>;
+			diff-channels = <6 7>;
+		};
+	};
