* Texas Instruments' ADC084S021
Required properties:
- compatible : Must be "ti,adc084s021"
- reg : SPI chip select number for the device
- vref-supply : The regulator supply for ADC reference voltage
- spi-cpol : Per spi-bus bindings
- spi-cpha : Per spi-bus bindings
- spi-max-frequency : Per spi-bus bindings
Example:
adc@0 {
compatible = "ti,adc084s021";
reg = <0>;
vref-supply = <&adc_vref>;
spi-cpol;
spi-cpha;
spi-max-frequency = <16000000>;
};
