From: Marcelo Schmitt <marcelo.schmitt1@xxxxxxxxx> This series adds support for AD7091R-2/-4/-8 ADCs which can do single shot or sequenced readings. Threshold events are also supported. Overall, AD7091R-2/-4/-8 are very similar to AD7091R-5 except they use SPI interface. This has been tested with raspberrypi and eval board on kernel 6.1 from ADI fork.
