Subject: [PATCH v6 0/4] Timestamp and PulSAR support for ad4000

Complement the ad4000 driver with a timestamp channel, a minor adjust in
transfer timing, and support for single-channel PulSAR devices.

Change log v5 -> v6
[IIO]
- Added commas at the end of channel lists in macros.
[Device tree]
- Made compatible property doc similar to other ADC dt-bindings.

Change log v4 -> v5
[IIO]
- No changes.
[Device tree]
- Added const items for fallback compatibles.

Change log v3 -> v4
[IIO]
- No changes.
[Device tree]
- Sorted compatible strings in alphabetical order.
- Left only fallback compatibles in allOf check list for adi,sdi-pin property.
- Improved patch description with explanation about how the AD4000 and PulSAR
  devices are different.

Change log v2 -> v3
[IIO]
- Reverted to direct assignment of ad4000_time_spec structs.
[Device tree]
- Moved ADAQ compatible strings to last compatible enum.

Change log v1 -> v2
- Added Suggested-by and Reviewed-by tags.
[IIO]
- Commented the removal of unused AD4000_TQUIET1_NS define in commit body.
- Made a common macro to assign ad4000_time_spec.
- Explicitly initialized PulSAR t_quiet2_ns with 0 as those don't need any quiet time.
- Improved PulSAR support commit description with more context.
- Dropped support for AD7694.
[Device tree]
- Made "cs" the default adi,sdi-pin value for PulSAR devices.
