Several people have asked me what is the deadline for submitting new 
drivers into Manila. I suspect many of these questions are related to 
the recent announcements that Cinder is requiring vendors to submit new 
drivers very early in the release (before milestone 1).

For Manila, there is no requirement to submit drivers early. We will 
enforce the same deadline for new drivers that we enforce for new 
features, which is: it must be merged by the Kilo-3 milestone date, 
unless an explicit exception is granted (exceptions are very rare). Now 
technically, this means that a submission of a new driver just a few 
weeks before K-3 could get reviewed and merged before the deadline, but 
that's only if the driver is flawless the first time or the reviewers 
provide quick feedback and the author responds immediately.

In reality things never go that smoothly, so here is my message to new 
driver authors: Do yourself a favor and submit your driver as early as 
possible. Expect the review process to take several weeks. Expect not to 
get a Feature Freeze exception. If you're working on a new driver, give 
us a heads up so we know it's coming and we can work with you to get it 
in the right shape to merge.
