Hi, I am sorry but I believe that they are ordered correctly and they
all should be part of this series as it ensures usb across all boards
and most of them depend on each other.
I think the order in which they have been sent makes the most sense:
adding what is needed by sam9x60, followed by sama7g5, sama5d2 and
finally enabling them all in the defconfigs.
I am not sure that sending multiple series that are dependent on each
other would make it easier.
