[PATCH 0/7] Add support for AD7091R-2/-4/-8

[<marcelo.schmitt@analog.com>]

From: Marcelo Schmitt <marcelo.schmitt1@gmail.com>

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.
