What’s the intent of trying to provide a unified interface here? I’m trying to understand what benefit we are going for, I get possibly wanting something to reduce duplication in drivers (help functions, library, etc). But do we really see benefit in a common interface for clients?

Are we really going to mix a OMAP mailbox controller with a client developed for some other SoC vendor?
