Kernel-4.18.0-80.el8_gpio-ts4800

  • 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>;
};
