Nice catch!
I'll fix it for the next version.
BTW did you test it (I didn't: I don't have any board with this SoC
family) ?
This separation was formerly done in the "at91 common clk" series but I
removed it
from the new version (which I will submit soon) to ease the review and
tests.
Best Regards,
Boris
