Thanks, Hans. I really should have figured that out on my own!
Do you think it's worth asking PeterR if he will change the default
Fedora armv7 config to CONFIG_REGULATOR_AXP20X=y rather than the
current CONFIG_REGULATOR_AXP20X=m? (I suspect that request might
carry more weight if it comes from you rather than me. ;)

Hans,
Do you have an opinion, (or anyone else for that matter), on what would be
the upstream preferred way of getting the axp20x regulator driver to
auto-load, from a DT reference, assuming it is built as a module? Something
like the attached patch? (Not tested, just thinking out loud.)

This is already fixed by this patch:

This is already fixed by this patch:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/dr...
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.

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...
------------
##

##
add_drivers+="cpufreq-dt sunxi-wdt"

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.

One other random thought, although along the same lines....
Need the anatop-regulator to autoload for the imx boards.
As you took the patch for the autoload of axp20x reg into your 4.2.x builds,
can you also pull a similar patch for anatop reg.
Think this should be in 4.3 already, but not in 4.2.

Do you think it's worth asking PeterR if he will change the default
Fedora armv7 config to CONFIG_REGULATOR_AXP20X=y rather than the
current CONFIG_REGULATOR_AXP20X=m?
Peter tries to keep the Fedora ARM kernel config as modular as possible
because of the wide variety of hardware it runs on + low amount of
memory on some hardware. So this will have to be kept modular (I know
this because I already asked :) ).
