1 Xilinx Zynq GPIO controller Device Tree Bindings
2 -------------------------------------------
5 - #gpio-cells : Should be two
6 - First cell is the GPIO line number
7 - Second cell is used to specify optional
9 - compatible : Should be "xlnx,zynq-gpio-1.0"
10 - clocks : Clock specifier (see clock bindings for details)
11 - gpio-controller : Marks the device node as a GPIO controller.
12 - interrupts : Interrupt specifier (see interrupt bindings for
14 - interrupt-parent : Must be core interrupt controller
15 - reg : Address and length of the register set for the device
20 compatible = "xlnx,zynq-gpio-1.0";
23 interrupt-parent = <&intc>;
24 interrupts = <0 20 4>;
25 reg = <0xe000a000 0x1000>;
