Hi Mike,
Nothing related to this thread, but if you have some time, could you
take a look at
the last version (v5) of the at91 CCF port ?
I know Nicolas was planning to add this for 3.14, and we'd like to have
your feedback
on the new dt bindings.
Best Regards,
Boris

This change belongs in patch #2. Please also update the kerneldoc above
