Here it is, the first one is based on linux-at91/linux-3.10-at91 branch, 
the second one is rebased on linux-3.18 (Is this the right way when 
playing with multiple branch?).

By the way, Wenyou fixed some bugs in the linux-3.10-at91 branch about 
slow clock mode which should IMHO be merged and pushed to other 
branches.

Sylvain
