Kernel-4.18.0-80.el8_ti-dac082s085

Texas Instruments 8/10/12-bit 2/4-channel DAC driver

Required properties:

• compatible: Must be one of:

       "ti,dac082s085"
       "ti,dac102s085"
       "ti,dac122s085"
       "ti,dac084s085"
       "ti,dac104s085"
       "ti,dac124s085"
  

• reg: Chip select number.
• spi-cpha, spi-cpol: SPI mode (0,1) or (1,0) must be used, so specify

       either spi-cpha or spi-cpol (but not both).
  

• vref-supply: Phandle to the external reference voltage supply.

For other required and optional properties of SPI slave nodes please refer to
../../spi/spi-bus.txt.

Example:
vref_2v5_reg: regulator-vref {
compatible = “regulator-fixed”;
regulator-name = “2v5”;
regulator-min-microvolt = <2500000>;
regulator-max-microvolt = <2500000>;
regulator-always-on;
};

dac@0 {
    compatible = "ti,dac082s085";
    reg = <0>;
    spi-max-frequency = <40000000>;
    spi-cpol;
    vref-supply = <&vref_2v5_reg>;
};
