Required properties:
- compatible: Should be "ti,adc128s052"
- reg: spi chip select number for the device
- vref-supply: The regulator supply for ADC reference voltage
Recommended properties:
- spi-max-frequency: Definition as per
Documentation/devicetree/bindings/spi/spi-bus.txt
Example:
adc@0 {
compatible = "ti,adc128s052";
reg = <0>;
vref-supply = <&vdd_supply>;
spi-max-frequency = <1000000>;
};
