Is there a linux driver for the AD7091R-8?

Question

Does there exist a linux driver for the AD7091R-8? Does libiio support that converter? 
 
 Thanks.

Thank you for that. In case others land here: TL;DR- you have to write it ( e.g. ad7091r8.c ): 
 
 The ad7091r-based device driver is instantiated by the ad7091r5 driver. https://github.com/analogdevicesinc/linux/blob/master/drivers/iio/adc/ad7091r-base.c https://github.com/analogdevicesinc/linux/blob/master/drivers/iio/adc/ad7091r5.c https://github.com/analogdevicesinc/linux/blob/master/Documentation/devicetree/bindings/iio/adc/adi%2Cad7091r5.yaml The AD7091R-5 is a 4-channel variant with an I2C interface. It would be relatively easy to support the AD7091R8. You need drivers/iio/adc/ad7091r8.c which is probed via the SPI BUS and then declares 8 channels. I think the register MAP should be pretty similar.

Hi OttoVonMetz ,

You can refer to this thread: (+) AD7091R-8 Linux-Treiber - Q&A - Linux Software Drivers - EngineerZone (analog.com).

And please be patient for this thread given above since it is in another language.
