+* TS-4800 FPGA's GPIO controller bindings
+
+Required properties:
+- compatible: Must be "technologic,ts4800-gpio".
+- #gpio-cells: Should be two. The first cell is the pin number.
+- reg: Physical base address of the controller and length
+ of memory mapped region.
+
+Optional property:
+- ngpios: See "gpio.txt"
+
+Example:
+
+gpio1: gpio {
+ compatible = "technologic,ts4800-gpio";
+ reg = <0x10020 0x6>;
+ ngpios = <8>;
+ gpio-controller;
+ #gpio-cells = <2>;
+};
