About where you added dtbs...

1/ As they are based on sama5d3, I would like to see them between
"at91-sama5d2_xplained.dtb" and "sama5d31ek.dtb"
2/ within this range, please sort all these 4 alphabetically
3/ don't laugh at me, I try to deal with our historical way of "sorting"
entries in this Makefile for AT91... ;-)
BTW, I realize now that your "at91-wb45n.dtb" entry from patch 1 should
go just after the "at91-kizboxmini.dts" (alphabetical order in
at91sam9x5 "location").

It must work, however...
I read in recent patches on dts directory that :
"We now require all at24 users to use the "atmel,<model>" fallback in
device tree for different manufacturers."
Moreover, I don't see giantec in the vendor prefix list.
