    1 Texas Instruments 8/10/12-bit 2/4-channel DAC driver
    2 
    3 Required 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 
   16 For other required and optional properties of SPI slave nodes please refer to
   17 ../../spi/spi-bus.txt.
   18 
   19 Example:
   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         };
