Hi, This driver does not build upon the previous patch set at all, so I didn't mark it as a v2. It is completely rewritten from scratch. I sent a note saying that the previous patch set was abandoned. There may be some similarities with the previous one, simply because the drivers do the same thing, but I don't think there is any need to compare it with the old driver I mailed out.
