[yocto] why there is no branch dizzy in meta-ti ?

[kris duff]

I work on dizzy branch of yocto/meta-ti, and I can see here : http://git.yoctoproject.org/cgit/cgit.cgi/meta-ti/refs/heads  that there is no dizzy branch. Why ?
Few weeks / month ago, the wifi on my boards stopped working after doing a repo sync ... (my bad) ...
I think one of the layer changed the wifi driver from libertas to mwifiex and since that moment, the wifi is not working properly. So I was wondering how can I fix the branch to dizzy ?
Thank you
Kris
