Required properties:



	- "compatible"		Must be set to "ti,dac7512"



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

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





Example:



	spi_master {

		dac7512: dac7512@0 {

			compatible = "ti,dac7512";

			reg = <0>; /* CS0 */

			spi-max-frequency = <1000000>;

		};

	};
