Tony,

I am not quite sure how much time it will take to merge common clock changes 
from Rajendra, since it is still in RFC stage and may take couple merge 
windows. I would recommend to merge clock-tree and hwmod patches atleast to 
the linux-next, so that it gets validated for some time and we atleast would 
be able to boot the BeagleBone (community board) from linux-next/master.
People can start further development using this on BeagleBone platform.

Based on common-clock migration activity on OMAP, we can certainly make 
decision on pushing it to Mainline (Linus's) tree. And also I will start 
basing AM33XX clocktree on Rajendra's patches, so that it will get merged at 
the same time.

Thanks,
Vaibhav
