Thanks, Peter.

One other thing to think about. Although the cpufreq-dt module will
autoload from dt ref, it needs to be in the initramfs image created by
dracut. This doesn't happen automatically. Currently have created a
/etc/dracut.conf.d/sunxi.conf with...

Weird, it appears to load and work post initrd with the BeagleBone.

In /sys/devices/system/cpu/cpu0/cpufreq I get all the bits I would
expect with cur/max/mon freqs etc.

I'll have a look when I get a spare moment on a A20 device.

I've pulled this patch into the F-23/4.2.x kernel, it'll be in the
4.2.2 build, it's already in rawhide.
