-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>;
-		};
