2017-12-07pinctrl: move gpio-axp209 to pinctrlQuentin Schulz
To prepare the driver for the upcoming pinctrl features, move the GPIO driver AXP209 from GPIO to pinctrl subsystem.

2017-12-07gpio: axp209: switch unsigned variables to unsigned intQuentin Schulz
Checkpatch complains with the following message: WARNING: Prefer 'unsigned int' to bare use of 'unsigned' Let's make it happy by switching over to unsigned int. Signed-off-by: Quentin Schulz <quentin.schulz@free-electrons.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-11-24gpio: axp209: use correct register for GPIO input statusQuentin Schulz
The GPIO input status was read from control register (AXP20X_GPIO[210]_CTRL) instead of status register (AXP20X_GPIO20_SS). Signed-off-by: Quentin Schulz <quentin.schulz@free-electrons.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-09-23gpio: axp209: Implement get_directionMaxime Ripard
Implement the get_direction callback for the GPIOs found in the AXP209 PMIC. Due to the way they are implemented, in the same register you have the muxing options, GPIO directions and GPIO values. Since you have no control over what value is there at reset, simply use output as the default.

2016-08-11gpio: Add AXP209 GPIO driverMaxime Ripard
The AXP209 PMIC has a bunch of GPIOs accessible, that are usually used to control LEDs or backlight. Add a driver for them Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
