Kernel-4.18.0-80.el8_max1118

• MAX1117/MAX1118/MAX1119 8-bit, dual-channel ADCs

Required properties:

• compatible: Should be one of
  • “maxim,max1117”
  • “maxim,max1118”
  • “maxim,max1119”
• reg: spi chip select number for the device
• (max1118 only) 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 = “maxim,max1118”;
reg = <0>;
vref-supply = <&vdd_supply>;
spi-max-frequency = <1000000>;
};
