As mentioned elsewhere, please fix all subjects, commit messages and
bindings to say Owl, not OWL. There's no need to upper-case it besides
defines.
Also, this title should mention Actions Semiconductor please, not just
the codename Owl.

What about S500? Are you expecting it to carry an S900 compatible? That
seems strange. Are there any differences in the implementations?
Otherwise looks okay.
