 Which of these patches will get into Havana 1?
The driver interface is pretty much the same in both patches and by design
it copies plugin interface (CRUD for each object).
Hopefully  https://review.openstack.org/#/c/28245/ will get in H-1 and you
could base your driver on the code from master.

will not be available isn’t it?
Device inventory is quite rich feature that needs some discussion. We
targeted it on H-3, meanwhile we've already started working on it.

Thanks,
Eugene.
