Next to Jan's comment about am335x having 7 cs signals, I just realized
the difference in compatible string between the gpmc and elm. The gpmc
refers to a real device (which is afaik how it should be done), but the
elm compatible is simply ti,am33xx-elm.

Presumably it should have been ti,am3352-elm in the binding instead?

Other than that it looks fine.
