Hi Rob,

So what seems to have happened here is only the i2c parts
of a dual bus driver got documented.  That happened as part
of a series adding a new part to the driver a while back.
(it's an old driver so probably only picked up dt support by accident)

An alternative would be to add the docs for the rest of the
parts supported by the driver - so have a unified doc for
the i2c and SPI parts.

Meh, it's probably simpler to just put that in as a separate
doc though rather than merge it with this one.  So we'll probably
have an adi,ad5686.yaml file again doing that once I get
round to writing one.

I'm assuming you'll pick this up?
