|
|
|
|
The node for this device must be a child node of a I2C controller, hence
|
|
all mandatory properties for your controller must be specified. See directory:
|
|
|
|
Documentation/devicetree/bindings/i2c
|
|
|
|
for more details.
|
|
|
|
Required properties:
|
|
- compatible: Must be one of the following, depending on the model:
|
|
adi,ad5272-020
|
|
adi,ad5272-050
|
|
adi,ad5272-100
|
|
adi,ad5274-020
|
|
adi,ad5274-100
|
|
|
|
Optional properties:
|
|
- reset-gpios: GPIO specification for the RESET input. This is an
|
|
active low signal to the AD5272.
|
|
|
|
Example:
|
|
ad5272: potentiometer@2f {
|
|
reg = <0x2F>;
|
|
compatible = "adi,ad5272-020";
|
|
reset-gpios = <&gpio3 6 GPIO_ACTIVE_HIGH>;
|
|
};
