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>;
|
||||||
|
};
|
||||||
|
};
