That's not a binding path. Probably bindings/nvmem/.

This schema will never be applied (your example would fail if it did) 
because we filter out matching on 'simple-mfd' as it is not valid on its 
own.

This literally means you have a node called 'child-node'.

This should be moved up a level removing 'simple-mfd'.

Not documented and also the wrong names (missing '#').
