This is complementary to the series titled "Add I2C support for
Allwinner SoCs" sent by Maxime today. We have no driver for the AXP20
PMIC yet, and the external header is left for the user to connect, so I
haven't added any device. This is still useful though, as it lets you
use I2C from userspace (i2cdetect, i2cdump, etc).

Emilio
