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. 8 9Optional property: 10- ngpios: See "gpio.txt" 11 12Example: 13 14gpio1: gpio { 15 compatible = "technologic,ts4800-gpio"; 16 reg = <0x10020 0x6>; 17 ngpios = <8>; 18 gpio-controller; 19 #gpio-cells = <2>; 20}; 21
