1* TS-4800 FPGA's GPIO controller bindings
2
3Required properties:
4- compatible: Must be "technologic,ts4800-gpio".
5- #gpio-cells: Should be two. The first cell is the pin number.
6- reg: Physical base address of the controller and length
7       of memory mapped region.

9Optional property:
10- ngpios: See "gpio.txt"

14gpio1: gpio {
15	compatible = "technologic,ts4800-gpio";
16	reg = <0x10020 0x6>;
17	ngpios = <8>;
18	gpio-controller;
19	#gpio-cells = <2>;
