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 Maxime Ripard (4): gpio: Add AXP209 GPIO driver mfd: axp20x: Add AXP209 GPIO driver to the mfd ARM: dt: axp209: Add AXP209 GPIO driver ARM: sun5i: chip: Add status LED .../devicetree/bindings/gpio/gpio-axp209.txt | 30 ++++ arch/arm/boot/dts/axp209.dtsi | 6 + arch/arm/boot/dts/sun5i-r8-chip.dts | 10 ++ drivers/gpio/Kconfig | 6 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-axp209.c | 162 +++++++++++++++++++++ drivers/mfd/axp20x.c | 3 + 7 files changed, 218 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/gpio-axp209.txt create mode 100644 drivers/gpio/gpio-axp209.c -- 2.9.0
