- 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

Thank you all for the help with this set,

----------------- 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.
