Are these changes in linux-next ? The mvebu maintainer Jason Cooper has
pulled the cpufreq support for Armada XP, so it will appear in
linux-next tomorrow. It would be good of the cpufreq-generic driver
improvements (to support one clock per CPU) were also part of
linux-next so that we could test that the combination works as expected
(of course, I did test locally, but I'd like to ensure it still works
in linux-next).

Could you get your tree in linux-next, or get your patches merged by
Rafael in his linux-next branch so that they will appear in linux-next ?

Thanks,

Thomas
