Hi Icenowy,

Interesting.
I did not find the documentation about the AXP813, but looking at the
Banana PI M3 driver (which seems a bit buggy), I found it was very
close to the AXP803.

Which more code do you think is needed for the AXP803?

Also, please, may you give me a pointer to the AXP813 documentation?
