| Xilinx Zynq GPIO controller Device Tree Bindings |
| ------------------------------------------- |
| |
| Required properties: |
| - #gpio-cells : Should be two |
| - First cell is the GPIO line number |
| - Second cell is used to specify optional |
| parameters (unused) |
| - compatible : Should be "xlnx,zynq-gpio-1.0" |
| - clocks : Clock specifier (see clock bindings for details) |
| - gpio-controller : Marks the device node as a GPIO controller. |
| - interrupts : Interrupt specifier (see interrupt bindings for |
| details) |
| - interrupt-parent : Must be core interrupt controller |
| - reg : Address and length of the register set for the device |
| |
| Example: |
| gpio@e000a000 { |
| #gpio-cells = <2>; |
| compatible = "xlnx,zynq-gpio-1.0"; |
| clocks = <&clkc 42>; |
| gpio-controller; |
| interrupt-parent = <&intc>; |
| interrupts = <0 20 4>; |
| reg = <0xe000a000 0x1000>; |
| }; |
