* Texas Instruments ADS8344 A/DC chip

Required properties:

 - compatible: Must be "ti,ads8344"

 - reg: SPI chip select number for the device

 - vref-supply: phandle to a regulator node that supplies the

   reference voltage

Recommended properties:

 - spi-max-frequency: Definition as per

		Documentation/devicetree/bindings/spi/spi-bus.txt

Example:

adc@0 {

	compatible = "ti,ads8344";

	reg = <0>;

	vref-supply = <&refin_supply>;

	spi-max-frequency = <10000000>;
