Yes, that is correct. The framework is different, but functionality
wise, you should be able to achieve the same (and a bit more).

Jassi is working through a newer version of the patches, so there would
be minor changes once the newer patchset is ready, but the core
framework/functionality shouldn't change much from above. Do take a look
at the framework (much of the explaination in header files) and see how
it fits your driver needs.
