+* Texas Instruments' ads124s08 and ads124s06 ADC chip
+
+Required properties:
+ - compatible: Should be "ti,ads124s08" or "ti,ads124s06"
+ - reg: spi chip select number for the device
+
+Recommended properties:
+ - spi-max-frequency: Definition as per
+ Documentation/devicetree/bindings/spi/spi-bus.txt
+ - spi-cpha: Definition as per
+ Documentation/devicetree/bindings/spi/spi-bus.txt
+
+Optional properties:
+ - vref-supply: The regulator supply for ADC reference voltage
+ - reset-gpios: GPIO pin used to reset the device.
+
+Example:
+adc@0 {
+ compatible = "ti,ads8688";
+ reg = <0>;
+ vref-supply = <&vdd_supply>;
+ spi-max-frequency = <1000000>;
+ spi-cpha;
+ reset-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
+};
