* Texas Instruments' ADC108S102 and ADC128S102 ADC chip



Required properties:

 - compatible: Should be "ti,adc108s102"

 - reg: spi chip select number for the device

 - vref-supply: The regulator supply for ADC reference voltage



Recommended properties:

 - spi-max-frequency: Definition as per

Example:

adc@0 {

	compatible = "ti,adc108s102";

	reg = <0>;

	vref-supply = <&vdd_supply>;

	spi-max-frequency = <1000000>;
