    1 APM X-Gene SoC GPIO controller bindings
    2 
    3 This is a gpio controller that is part of the flash controller.
    4 This gpio controller controls a total of 48 gpios.
    5 
    6 Required properties:
    7 - compatible: "apm,xgene-gpio" for X-Gene GPIO controller
    8 - reg: Physical base address and size of the controller's registers
    9 - #gpio-cells: Should be two.
   10         - first cell is the pin number
   11         - second cell is used to specify the gpio polarity:
   12                 0 = active high
   13                 1 = active low
   14 - gpio-controller: Marks the device node as a GPIO controller.
   15 
   16 Example:
   17         gpio0: gpio0@1701c000 {
   18                 compatible = "apm,xgene-gpio";
   19                 reg = <0x0 0x1701c000 0x0 0x40>;
   20                 gpio-controller;
   21                 #gpio-cells = <2>;
   22         };
