-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@e000a000 {
-		#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>;
-	};
