Why?

Bindings are for h/w, not drivers. You are adding a property, not a
node. Would be nice to know what 'iep' is without having to look at the
diff (e.g. when running 'git log').

phandle-array really means matrix, so you need to fully describe the
items constraints.

2 phandles or 1 phandle and 1 arg? Looks like the former from the
example, so:

maxItems: 2
items:
maxItems: 1
