TI DAC7512 DEVICETREE BINDINGS

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>;
		};
	};
