-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" or
- "xlnx,zynqmp-gpio-1.0" or "xlnx,versal-gpio-1.0
- or "xlnx,pmc-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-controller : Marks the device node as an interrupt controller.
-- #interrupt-cells : Should be 2. The first cell is the GPIO number.
- The second cell bits[3:0] is used to specify trigger type and level flags:
- 1 = low-to-high edge triggered.
- 2 = high-to-low edge triggered.
- 4 = active high level-sensitive.
- 8 = active low level-sensitive.
-- reg : Address and length of the register set for the device
-
-Example:
- gpio@...0a000 {
- #gpio-cells = <2>;
- compatible = "xlnx,zynq-gpio-1.0";
- clocks = <&clkc 42>;
- gpio-controller;
- interrupt-parent = <&intc>;
- interrupts = <0 20 4>;
- interrupt-controller;
- #interrupt-cells = <2>;
- reg = <0xe000a000 0x1000>;
- };
