It turns out that this patch while necessary is not sufficient and I
also needed the following for full cpufreq autoloading on Cubietruck
with Debian's modular kernel config.

Cheers,
Ian.

Subject: [PATCH] regulator: axp20x: Add module alias

This allows the module to be autoloaded.

Together with 07949bf9c63c ("cpufreq: dt: allow driver to boot
automatically") this is sufficient to allow a modular kernel (such
as Debian's) to enable cpufreq on a Cubietruck.
