Subject: [PATCH v2 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.

This series was tested with ADAQ4003, AD7687, and AD7691 on CoraZ7 board.

Link to v1: https://lore.kernel.org/linux-iio/cover.1731626099.git.marcelo.schmitt@analog.com/

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.

Additional comments in patch number 1.
