-Cavium ThunderX/OCTEON-TX GPIO controller bindings
-
-Required Properties:
-- reg: The controller bus address.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells: Must be 2.
-  - First cell is the GPIO pin number relative to the controller.
-  - Second cell is a standard generic flag bitfield as described in gpio.txt.
-
-Optional Properties:
-- compatible: "cavium,thunder-8890-gpio", unused as PCI driver binding is used.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Must be present and have value of 2 if
-                    "interrupt-controller" is present.
-  - First cell is the GPIO pin number relative to the controller.
-  - Second cell is triggering flags as defined in interrupts.txt.
-
-Example:
-
-gpio_6_0: gpio@6,0 {
-	compatible = "cavium,thunder-8890-gpio";
-	reg = <0x3000 0 0 0 0>; /*  DEVFN = 0x30 (6:0) */
-	gpio-controller;
-	#gpio-cells = <2>;
-	interrupt-controller;
-	#interrupt-cells = <2>;
-};
