[PATCH v3 0/8] iio: adc: ad7606: Improvements

[Guillaume Stols]

This series adds the following improvements over the current AD7606's
driver implementation:

- Fix wrong usage of gpio array
- Fix standby that was documented as ACTIVE_LOW but handled in the
  driver as if it was ACTIVE_HIGH
- Improve dt-bindings documentation
- Switch mutex lock to scoped guard

Changes in v3:
- Remove the two first patches that were already picked up.
- Add styling corrections.
- [Patch 6/8] Improve commit message.
- [Patch 8/8] Replace every scoped_guard by simple guard.
- Link to v2: https://lore.kernel.org/r/20240628-cleanup-ad7606-v2-0-96e02f90256d@xxxxxxxxxxxx

Changes in v2:
- Change scoped guard to guard(mutex)(&st->lock). This was tested with
  Rob's bot condition, and seems not to generate warning anymore.
- Reorder the commits for avoiding bisection issues and respect commit
  priority rules.
- Add vdrive-supply to required properties.
- Separate cosmetic changes from content ones in dt-binding
  descriptions.
- Move maxItems changes (and plural in descriptions) to the commit that
  adds conditions.
- Link to v1: https://lore.kernel.org/r/20240618-cleanup-ad7606-v1-0-f1854d5c779d@xxxxxxxxxxxx
