1Analog Devices AD7303 DAC device driver 2 3Required properties: 4 - compatible: Must be "adi,ad7303" 5 - reg: SPI chip select number for the device 6 - spi-max-frequency: Max SPI frequency to use (< 30000000) 7 - Vdd-supply: Phandle to the Vdd power supply 8 9Optional properties: 10 - REF-supply: Phandle to the external reference voltage supply. This should 11 only be set if there is an external reference voltage connected to the REF 12 pin. If the property is not set Vdd/2 is used as the reference voltage. 13 14Example: 15 16 ad7303@4 { 17 compatible = "adi,ad7303"; 18 reg = <4>; 19 spi-max-frequency = <10000000>; 20 Vdd-supply = <&vdd_supply>; 21 adi,use-external-reference; 22 REF-supply = <&vref_supply>; 23 }; 24
