    1 Aspeed GPIO controller Device Tree Bindings
    2 -------------------------------------------
    3 
    4 Required properties:
    5 - compatible            : Either "aspeed,ast2400-gpio", "aspeed,ast2500-gpio",
    6                                         or "aspeed,ast2600-gpio".
    7 
    8 - #gpio-cells           : Should be two
    9                           - First cell is the GPIO line number
   10                           - Second cell is used to specify optional
   11                             parameters (unused)
   12 
   13 - reg                   : Address and length of the register set for the device
   14 - gpio-controller       : Marks the device node as a GPIO controller.
   15 - interrupts            : Interrupt specifier (see interrupt bindings for
   16                           details)
   17 - interrupt-controller  : Mark the GPIO controller as an interrupt-controller
   18 
   19 Optional properties:
   20 
   21 - clocks                : A phandle to the clock to use for debounce timings
   22 - ngpios                : Number of GPIOs controlled by this controller. Should be set
   23                                   when there are multiple GPIO controllers on a SoC (ast2600).
   24 
   25 The gpio and interrupt properties are further described in their respective
   26 bindings documentation:
   27 
   28 - Documentation/devicetree/bindings/gpio/gpio.txt
   29 - Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
   30 
   31   Example:
   32         gpio@1e780000 {
   33                 #gpio-cells = <2>;
   34                 compatible = "aspeed,ast2400-gpio";
   35                 gpio-controller;
   36                 interrupts = <20>;
   37                 reg = <0x1e780000 0x1000>;
   38                 interrupt-controller;
   39         };
