   1 AXP209 GPIO controller
   2
   3 This driver follows the usual GPIO bindings found in
   4 Documentation/devicetree/bindings/gpio/gpio.txt
   5
   6 Required properties:
   7 - compatible: Should be "x-powers,axp209-gpio"
   8 - #gpio-cells: Should be two. The first cell is the pin number and the
   9   second is the GPIO flags.
  10 - gpio-controller: Marks the device node as a GPIO controller.
  11
  12 This node must be a subnode of the axp20x PMIC, documented in
  13 Documentation/devicetree/bindings/mfd/axp20x.txt
  14
  15 Example:
  16
  17 axp209: pmic@34 {
  18         compatible = "x-powers,axp209";
  19         reg = <0x34>;
  20         interrupt-parent = <&nmi_intc>;
  21         interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
  22         interrupt-controller;
  23         #interrupt-cells = <1>;
  24
  25         axp_gpio: gpio {
  26                 compatible = "x-powers,axp209-gpio";
  27                 gpio-controller;
  28                 #gpio-cells = <2>;
  29         };
  30 };
