+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>;
