The example uses 'adi,ad5686', but the schema fails to document it. Given
the filename and there is a similar part AD5686, let's just add the
compatible strings including the 'r' variant.

There are two variants of this chip. One with a SPI interface and one 
with a I2C interface. This binding document only describes the I2C 
variants. But the ad5686 is a SPI variant.

I think this is a typo and we should replace ad5686 with ad5696, 
including the document name.

Right, I should have noticed that.

Though we do frequently document both I2C and SPI variants in the same 
binding, given there's no existing SPI support and the example is wrong 
I agree.

Ah, this is what I get for reading my emails out of order.

There is existing SPI driver support if that's what you mean
we just haven't documented the binding for it.

Should work via the fallbacks in SPI that drop the vendor id off then match
on the rest.  As I mentioned in reply to v2. It's an old driver so
kind of got DT support by accident.

I'll play catch up at some stage soon on missing binding docs,
(I suspect there are quite a few for older IIO drivers)

Thanks,

Jonathan
