+Analog Devices AD7768-1 ADC device driver
+
+Required properties for the AD7768-1:
+
+- compatible: Must be "adi,ad7768-1"
+- 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
+- vref-supply: vref supply can be used as reference for conversion
+- adi,sync-in-gpios: must be the device tree identifier of the SYNC-IN pin. A pulse
+ is always required if the configuration is changed in any way, for example
+ if the filter decimation rate changes. As the line is active low, it should
+ be marked GPIO_ACTIVE_LOW.
+
+Example:
+
+ adc@0 {
+ compatible = "adi,ad7768-1";
+ reg = <0>;
+ spi-max-frequency = <2000000>;
+ spi-cpol;
+ spi-cpha;
+ vref-supply = <&adc_vref>;
+ interrupts = <25 IRQ_TYPE_EDGE_RISING>;
+ interrupt-parent = <&gpio>;
+ adi,sync-in-gpios = <&gpio 22 GPIO_ACTIVE_LOW>;
+ clocks = <&ad7768_mclk>;
+ clock-names = "mclk";
+ };
