I refer back to our previous discussion (https://lkml.org/lkml/2015/10/8/661).
This doesn't add anything and makes the binding name unnecessarily long. Why is
this being enforced? Whoever uses the binding will have to look at the
documentation to understand which values are valid anyway, so this seems like
cruft.
