Subject to the discussion you had with David about us only normally
adding a dt-binding as part of the final series that moves a driver
out of staging.  This looks fine to me.

Note I've been hopefully checking analog.com every 6 months or so for
the ad7817 to go obsolete - (no luck yet!) - hence I haven't deleted
the driver despite no one getting it into a reasonable state for
many years. If you are interested in doing that work then great!
Maybe the Analog devices folk can help you out with testing etc.
