Alexandre, it seems okay but... I would like all new AT91 SoC converted
to DT to include the CCF from the beginning. It will prevent to have a
temporary phase were people start to use the DT and then have to move
again to another DT description with CCF.

Please follow what Jean-Jacques did for sam9261 DT + CCF.

I agree that it would be better but that is not done on other at91sam9
socs. Nicolas, can you comment ?

I do agree with Thomas. It is true that it is missing in other sam9 dtsi
files.
On the other hand, it is present in sama5d3.dtsi file. So we might have
figured it out at some point ;-)
