Key thing here is that we generally don't take bindings for drivers
that are in staging and adis16203 remains there.

This patch looks good for when/if the driver is moved out of
staging.  There have been various series on list for that so
perhaps ask those authors what current status is (just reply
to that series).

e.g. 

https://lore.kernel.org/linux-iio/20260401162458.88110-1-nothingchang@mirrorstack.ai/

Which is the parent of the last link below and I think the last of
various attempts to do this.
