* 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 */
|
|
};
