Required properties:

 - compatible: Has to contain one of the following:

	lltc,ltc2632-l12

	lltc,ltc2632-l10

	lltc,ltc2632-l8

	lltc,ltc2632-h12

	lltc,ltc2636-h12

	lltc,ltc2636-h10

	lltc,ltc2636-h8



Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt

apply. In particular, "reg" and "spi-max-frequency" properties must be given.



Optional properties:

	- vref-supply: Phandle to the external reference voltage supply. This should

	  only be set if there is an external reference voltage connected to the VREF

	  pin. If the property is not set the internal reference is used.



Example:



	vref: regulator-vref {

		compatible = "regulator-fixed";

		regulator-name = "vref-ltc2632";

		regulator-min-microvolt = <1250000>;

		regulator-max-microvolt = <1250000>;

		regulator-always-on;

	};



	spi_master {

		dac: ltc2632@0 {

			compatible = "lltc,ltc2632-l12";

			reg = <0>; /* CS0 */

			spi-max-frequency = <1000000>;

			vref-supply = <&vref>; /* optional */

		};

	};
