The 'adi,adxl345' definition is a duplicate as there's a full binding in:
Documentation/devicetree/bindings/iio/accel/adi,adxl345.yaml

The trivial-devices binding doesn't capture that 'adi,adxl346' has a
fallback compatible 'adi,adxl345', so let's add it to adi,adxl345.yaml.

I assume it is my schema understanding that is poor.
But I cannot parse the above.

The mix of items, enum and const confuses me.

I guess that if I am confused then others may end in the same situation.
Can we improve readability here or amybe add a comment?

compatible can be one of 3 possibilities:
"adi,adxl346", "adi,adxl345"
"adi,adxl345"
"adi,adxl375"

For a single entry, 'items' can be omitted.

example-schema.yaml explains this to some extent. I'd rather improve that.
