* 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>; };
