Hi,

I'm sure the community will be happy to merge the driver back into the
repository.

Still, I would recommend you looking at the "How To Contribute a driver to
Cinder" guide [1] and the "Third Party CI Requirement Policy"
documentation [2], and then adding this topic to Wednesday's meeting [3]
and go to the meeting to ensure that everybody is on board with it.

Best regards,
Gorka.
