does this unified API affects userspace interface, internal kernel
interface or both?

I'm happy about any progress on this. It's not really urgent for me to
get the driver into mainline. A helpful and useable userspace interface
is more important to me. So i want to send my comments/requirements
about the API and post the mxs driver after the definition of the
unified API.

Does this answer your question?
