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@xxxxxxxxxx/ 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.
