Subject: [PATCH v4 0/5] ad7380: add adaq4370-4 and adaq4380-4 support
Hello,
This series add support for adaq4370-4 (2MSPS) and adaq4380-4 (4MSPS)
which are quad-channel precision data acquisition signal chain μModule
solutions compatible with the ad738x family, with the following differences:
- pin selectable gain in front of each 4 adc
- internal reference is 3V derived from refin-supply (5V)
- additional supplies
This series depends on [1] which fix several supplies issues

Changes in v4:
- Adding a new patch to pull out a local "dev" variable to shorten some
long lines
- Fix few minor comment from Jonathan Cameron and David Lechner
- Link to v3: https://lore.kernel.org/r/20241024-ad7380-add-adaq4380-4-support-v3-0-6a29bd0f79da@baylibre.com
Changes in v3:
bindings:
- remove item from channel reg property (should be part of V2, but get
lost during rebase)
- remove unnecessary () for channel property
- keep consistent quotes
- Link to v2: https://lore.kernel.org/r/20241023-ad7380-add-adaq4380-4-support-v2-0-d55faea3bedf@baylibre.com
Changes in v2:
- fix commit messages and documentation about the gain: pin selectable
gain instead of configurable gain
- add the enum of available gains inthe binding and array of available
gains in the driver as ad4000 series
- in the bindings, remove item from channel reg property
- in the bindings, merge additional supplies and channel properties inside
the same if branch for adaq devices
- fix comment as suggested by Jonathan in the driver
- Link to v1: https://lore.kernel.org/r/20241015-ad7380-add-adaq4380-4-support-v1-0-d2e1a95fb248@baylibre.com
