    1 * Marvell PXA GPIO controller
    2 
    3 Required properties:
    4 - compatible : Should be "intel,pxa25x-gpio", "intel,pxa26x-gpio",
    5                 "intel,pxa27x-gpio", "intel,pxa3xx-gpio",
    6                 "marvell,pxa93x-gpio", "marvell,mmp-gpio",
    7                 "marvell,mmp2-gpio" or marvell,pxa1928-gpio.
    8 - reg : Address and length of the register set for the device
    9 - interrupts : Should be the port interrupt shared by all gpio pins.
   10   There're three gpio interrupts in arch-pxa, and they're gpio0,
   11   gpio1 and gpio_mux. There're only one gpio interrupt in arch-mmp,
   12   gpio_mux.
   13 - interrupt-names : Should be the names of irq resources. Each interrupt
   14   uses its own interrupt name, so there should be as many interrupt names
   15   as referenced interrupts.
   16 - interrupt-controller : Identifies the node as an interrupt controller.
   17 - #interrupt-cells: Specifies the number of cells needed to encode an
   18   interrupt source.
   19 - gpio-controller : Marks the device node as a gpio controller.
   20 - #gpio-cells : Should be two.  The first cell is the pin number and
   21   the second cell is used to specify flags. See gpio.txt for possible
   22   values.

   24 Example for a MMP platform:
   25 
   26         gpio: gpio@d4019000 {
   27                 compatible = "marvell,mmp-gpio";
   28                 reg = <0xd4019000 0x1000>;
   29                 interrupts = <49>;
   30                 interrupt-names = "gpio_mux";
   31                 gpio-controller;
   32                 #gpio-cells = <2>;
   33                 interrupt-controller;
   34                 #interrupt-cells = <1>;
   35       };
   36 
   37 Example for a PXA3xx platform:
   38 
   39         gpio: gpio@40e00000 {
   40                 compatible = "intel,pxa3xx-gpio";
   41                 reg = <0x40e00000 0x10000>;
   42                 interrupt-names = "gpio0", "gpio1", "gpio_mux";
   43                 interrupts = <8 9 10>;
   44                 gpio-controller;
   45                 #gpio-cells = <0x2>;
   46                 interrupt-controller;
   47                 #interrupt-cells = <0x2>;
   48         };
