Subject: [PATCH 0/4] Add AXP209 GPIO driver

Hi,

The axp209 PMIC used in combination to some Allwinner SoCs has a bunch
of GPIOs accessible. Some boards use these to control their backlight
or a few LEDs.

There's supposed to be 4 of them, but the fourth one has a different
configuration register scheme, and I couldn't find any board that was
using this GPIO. It will be probably be supported eventually, but
until then, we support only the first 3 GPIOs.

Let me know what you think,
Maxime
