• Texas Instruments’ ADC128S052, ADC122S021 and ADC124S021 ADC chip

Required properties:

• compatible: Should be “ti,adc128s052”, “ti,adc122s021” or “ti,adc124s021”
• 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
