* Maxim Linear-Taper Digital Potentiometer MAX5481-MAX5484

The node for this driver must be a child node of a SPI controller, hence
all mandatory properties described in

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

must be specified.

Required properties:
	- compatible:  	Must be one of the following, depending on the
			model:
			"maxim,max5481"
			"maxim,max5482"
			"maxim,max5483"
			"maxim,max5484"

Example:
max548x: max548x@0 {
	compatible = "maxim,max5482";
	spi-max-frequency = <7000000>;
	reg = <0>; /* chip-select */
};
