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>;
|
||||
};
