The GPIOs present in the AXP209 PMIC have multiple functions. They
typically allow a pin to be used as GPIO input or output and can also be
used as ADC or regulator for example.[1]

This adds the possibility to use all functions of the GPIOs present in
the AXP209 PMIC thanks to pinctrl subsystem.

I need Maxime's review on this patch.

 .../devicetree/bindings/gpio/gpio-axp209.txt       |  28 +-

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
