Analog Devices AD7303 DAC device driver
|
|
|
|
Required properties:
|
|
- compatible: Must be "adi,ad7303"
|
|
- reg: SPI chip select number for the device
|
|
- spi-max-frequency: Max SPI frequency to use (< 30000000)
|
|
- Vdd-supply: Phandle to the Vdd power supply
|
|
|
|
Optional properties:
|
|
- REF-supply: Phandle to the external reference voltage supply. This should
|
|
only be set if there is an external reference voltage connected to the REF
|
|
pin. If the property is not set Vdd/2 is used as the reference voltage.
|
|
|
|
Example:
|
|
|
|
ad7303@4 {
|
|
compatible = "adi,ad7303";
|
|
reg = <4>;
|
|
spi-max-frequency = <10000000>;
|
|
Vdd-supply = <&vdd_supply>;
|
|
adi,use-external-reference;
|
|
REF-supply = <&vref_supply>;
|
|
};
