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. Link: https://wiki.analog.com/resources/tools-software/linux-drivers/iio-adc/ad7091r8 I ran get_maintainers on driver files but completely forgot to run it on the yaml doc, my bad. I made the changes requested so far. For v2, I also ran dt_binding_check on iio testing branch to check out for any additional dt-schema issues. None reported. Didn't see any other warn after running Sparse, Smatch, and Coccicheck. I get a warn from checkpatch about IIO_DMA_MINALIGN which I don't know how to fix :( Change log v1 -> v2: - Added device tree related To/Cc recipients. - Removed extra print of error code - $ref: "adc.yaml" -> $ref: adc.yaml - Fixed defined but not used build warn - Moved dt documentation of required properties to after patternProperties. - Removed incorrect return before regmap_update_bits().
