I have an Olimex OlinuXino-A20-Lime2 which does not report power statistics
(voltage, current) in /sys/class/power_supply
This is remedied decompiling the DTB to DTS in boot, applying the following
patch and
recompiling into a DTC:

On the following reboot, axp20x_usb_power.ko will be loaded and
/sys/class/power_supply will be there:

I presume this would need to be fixed upstream in
arch/arm/boot/dts/un7i-a20-olinuxino-lime2.dts
but I don't know where to direct that specific bug report.
The specific file affected in the Debian package is
/usr/lib/linux-image-4.4.0-1-armmp-lpae/sun7i-a20-olinuxino-lime2.dtb.
See Documentation/devicetree/bindings/power_supply/axp20x_usb_power.txt for
documentation on the bindings introduced.
