* 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
Optional properties:
- 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>;
};
