Kernel-4.18.0-80.el8_max1027-adc

• Maxim 1027/1029/1031 Analog to Digital Converter (ADC)

Required properties:

• compatible: Should be “maxim,max1027” or “maxim,max1029” or “maxim,max1031”
• reg: SPI chip select number for the device
• interrupt-parent: phandle to the parent interrupt controller
  see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
• interrupts: IRQ line for the ADC
  see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt

Recommended properties:

• spi-max-frequency: Definition as per

                 Documentation/devicetree/bindings/spi/spi-bus.txt
  

Example:
adc@0 {
compatible = “maxim,max1027”;
reg = <0>;
interrupt-parent = <&gpio5>;
interrupts = <15 IRQ_TYPE_EDGE_RISING>;
spi-max-frequency = <1000000>;
};
