* Linear Technology / Analog Devices LTC2497 ADC

Required properties:
 - compatible: Must be "lltc,ltc2497"
 - reg: Must contain the ADC I2C address
 - vref-supply: The regulator supply for ADC reference voltage

Example:
	ltc2497: adc@76 {
		compatible = "lltc,ltc2497";
		reg = <0x76>;
		vref-supply = <&ltc2497_reg>;
	};
