Hi Jan,

I have moved you question to the Embedded sub-section where your question will be viewed by more of our experienced embedded community.

The driver you want is found in the linux kernel at /drivers/staging/iio/adc/ad7192.c . You will need to build this driver into the kernel you are using (or use it as a loadable module I suppose).

the device tree node will need to be a child node of your SPI controller node, and look something like:

&spi0 {
    ad7193: ad7193@0{
        compatible = "adi,ad7193";
        spi-max-frequency = <5000000>;
        reg = <0>;
    };
};
