Mike, Boris,
I will take the series in the at91 git tree that will go through arm-soc.
This way, I can synchronize with the other series cooked by Boris which actually implements the CCF for sama5d3 SoCs.
Mike, I keep you in the CC list of my upcoming pull-request to Olof, Kevin and Arnd.
Thanks, bye,
