I think it would be beneficial if this consisted of two very clearly
separated parts:

1. the actual recommended binding - so people writing new
devicetrees know what to do

2. the legacy bindings which "also work", which is important
to know when working with legacy devicetrees

At least, that's what I would want if I put myself in a user's
shoes.
