I need Maxime's review on this patch.

Also move the bindings to pinctrl/pinctrl-axp209.txt

>  drivers/gpio/gpio-axp209.c                         | 551 ++++++++++++++++++---

Combined drivers should be in drivers/pinctrl/*.

Make a separate patch moving the driver to
drivers/pinctrl/pinctrl-axp209.c (remember -M to git format-patch)
augment Kconfig and Makefile in both subsystems and make
these patches on top of that.

I will deal with cross-merging the result between the GPIO
and pin control trees.

Yours,
Linus Walleij
