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
Changes from v1:
- Use gpiochip_add_data and gpiochip_get_data
- Drop unneeded headers
- Make sure gpio_get returns 0 or 1
- Made sure it compiles
- Rebased on linux-next
