1*4882a593SmuzhiyunAnalog Devices AD7303 DAC device driver 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunRequired properties: 4*4882a593Smuzhiyun - compatible: Must be "adi,ad7303" 5*4882a593Smuzhiyun - reg: SPI chip select number for the device 6*4882a593Smuzhiyun - spi-max-frequency: Max SPI frequency to use (< 30000000) 7*4882a593Smuzhiyun - Vdd-supply: Phandle to the Vdd power supply 8*4882a593Smuzhiyun 9*4882a593SmuzhiyunOptional properties: 10*4882a593Smuzhiyun - REF-supply: Phandle to the external reference voltage supply. This should 11*4882a593Smuzhiyun only be set if there is an external reference voltage connected to the REF 12*4882a593Smuzhiyun pin. If the property is not set Vdd/2 is used as the reference voltage. 13*4882a593Smuzhiyun 14*4882a593SmuzhiyunExample: 15*4882a593Smuzhiyun 16*4882a593Smuzhiyun ad7303@4 { 17*4882a593Smuzhiyun compatible = "adi,ad7303"; 18*4882a593Smuzhiyun reg = <4>; 19*4882a593Smuzhiyun spi-max-frequency = <10000000>; 20*4882a593Smuzhiyun Vdd-supply = <&vdd_supply>; 21*4882a593Smuzhiyun adi,use-external-reference; 22*4882a593Smuzhiyun REF-supply = <&vref_supply>; 23*4882a593Smuzhiyun }; 24
