-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

-       reg = <0>;
-       interrupt-parent = <&gpio5>;
-       interrupts = <15 IRQ_TYPE_EDGE_RISING>;
