1Texas Instruments 8/10/12-bit 2/4-channel DAC driver 2 3Required properties: 4 - compatible: Must be one of: 5 "ti,dac082s085" 6 "ti,dac102s085" 7 "ti,dac122s085" 8 "ti,dac084s085" 9 "ti,dac104s085" 10 "ti,dac124s085" 11 - reg: Chip select number. 12 - spi-cpha, spi-cpol: SPI mode (0,1) or (1,0) must be used, so specify 13 either spi-cpha or spi-cpol (but not both). 14 - vref-supply: Phandle to the external reference voltage supply. 15 16For other required and optional properties of SPI slave nodes please refer to 17../../spi/spi-bus.txt. 18 19Example: 20 vref_2v5_reg: regulator-vref { 21 compatible = "regulator-fixed"; 22 regulator-name = "2v5"; 23 regulator-min-microvolt = <2500000>; 24 regulator-max-microvolt = <2500000>; 25 regulator-always-on; 26 }; 27 28 dac@0 { 29 compatible = "ti,dac082s085"; 30 reg = <0>; 31 spi-max-frequency = <40000000>; 32 spi-cpol; 33 vref-supply = <&vref_2v5_reg>; 34 }; 35
