AXP209 GPIO controller
This driver follows the usual GPIO bindings found in
Documentation/devicetree/bindings/gpio/gpio.txt
Required properties:
- compatible: Should be "x-powers,axp209-gpio"
- #gpio-cells: Should be two. The first cell is the pin number and the
second is the GPIO flags.
- gpio-controller: Marks the device node as a GPIO controller.
This node must be a subnode of the axp20x PMIC, documented in
Documentation/devicetree/bindings/mfd/axp20x.txt
Example:
axp209: pmic@34 {
compatible = "x-powers,axp209";
reg = <0x34>;
interrupt-parent = <&nmi_intc>;
interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
interrupt-controller;
#interrupt-cells = <1>;
axp_gpio: gpio {
compatible = "x-powers,axp209-gpio";
gpio-controller;
#gpio-cells = <2>;
};
};
