From: Alisa-Dariana Roman <alisa.roman@analog.com>

Hello,

Here is the updated patch that adds fast settling support for AD7193. I
also added 2 commits to clean up the driver that should be applied
beforehand.

Please consider applying the patches in order.

Thank you!

v3 -> v4
	- two commits from the previous series were already applied to
	  the tree
	- add two new commits for cleaning up
	- use standard ABI for fast settling feature instead of creating
	  new attributes
	Link: https://lore.kernel.org/all/20230924215148.102491-1-alisadariana@gmail.com/

v2 -> v3
        - move comment line above
        - correct FIELD_PREP to FIELD_GET where needed
        - remove unnecessary !!
        - "rms" -> "RMS"
        Link: https://lore.kernel.org/all/20230920003342.118813-1-alisadariana@gmail.com/

v1 -> v2
        - replace old macros with FIELD_PREP() in commit "Use bitfield
          access macros"
        - update the other commits accordingly
        Link: https://lore.kernel.org/all/20230918214854.252781-1-alisadariana@gmail.com/

Kind regards,

From: Alisa-Dariana Roman <alisa.roman@analog.com>

Add fast settling mode support for AD7193.

Add two new device specific attributes: oversampling_ratio and
oversampling_ratio_available.

For AD7193 the user can set the average factor by writing to
oversampling_ratio. The possible values are exposed when reading
oversampling_ratio_available.
