Picking any of the recently converted drivers or recently merged atomic
drivers should be fairly informative. Overall conversion procedure is
detailed in

http://blog.ffwll.ch/2014/11/atomic-modeset-support-for-kms-drivers.html
http://blog.ffwll.ch/2015/01/update-for-atomic-display-updates.html

And ofc there's the kerneldoc stuff in the drm docbook. If you have
questions probably best to ask them in #dri-devel irc, most of the people
who've done atomic conversions hang out there and can help out.

Cheers, Daniel
