| 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>; |
| }; |
