Change log v3 -> v4: - Patch 1: checkpatch patch * Changed __aligned regex string. - Patch 2: alert handling fix * Applied David's suggestion [1] to pass iio_dev on to IRQ thread handler. - Patches 6, 7, 9 * Removed ad7091r prefix from callback function names. - New Patch 7: Remove uneeded probe parameters * Removed id->name and regmap from probe paramenters. - Patch 8 (now Patch 9): Enable internal vref * Not expecting NULL return from regulator_get_optional() anymore; * Reverted to previous probe defer handling. - Patch 10 (now Patch 11): dt doc * Extending existing ad7091r5 dt doc instead of creating a new one; * Added VDD and VDRIVE supplies to dt doc; * Removed channel property from dt doc; * Interrupt description, interrupt constraint check, example indentation improvements. - Patch 12 (now Patch 13): add ad7091r8 patch * Neats to macros, gpio setups, and probe parameters. - Patch 13 (now Patch 14): * Made use of wild cards in MAINTAINERS file. - New Patch (Patch 15): event configuration callbacks [1]: https://lore.kernel.org/linux-iio/CAMknhBHCYicEL_xhumBQMUm=HBVb=7dLrYsK8Zj2o7RodvMarw@mail.gmail.com/ Thank you all for the help with this set, Marcelo ----------------- Context ----------------- 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. Changes have been tested with raspberrypi and eval board on raspberrypi kernel 6.7-rc3 from raspberrypi fork.
