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>;
};
};
