Required properties:
|
|
- compatible: Must be one of:
|
|
"ti,dac082s085"
|
|
"ti,dac102s085"
|
|
"ti,dac122s085"
|
|
"ti,dac084s085"
|
|
"ti,dac104s085"
|
|
"ti,dac124s085"
|
|
- reg: Chip select number.
|
|
- spi-cpha, spi-cpol: SPI mode (0,1) or (1,0) must be used, so specify
|
|
either spi-cpha or spi-cpol (but not both).
|
|
- vref-supply: Phandle to the external reference voltage supply.
|
|
|
|
For other required and optional properties of SPI slave nodes please refer to
|

|
Example:
|
|
vref_2v5_reg: regulator-vref {
|
|
compatible = "regulator-fixed";
|
|
regulator-name = "2v5";
|
|
regulator-min-microvolt = <2500000>;
|
|
regulator-max-microvolt = <2500000>;
|
|
regulator-always-on;
|
|
};
|
|
|
|
dac@0 {
|
|
compatible = "ti,dac082s085";
|
|
reg = <0>;
|
|
spi-max-frequency = <40000000>;
|
|
spi-cpol;
|
|
vref-supply = <&vref_2v5_reg>;
|
|
};
