Kernel-4.18.0-80.el8_gpio-zevio

Zevio GPIO controller

Required properties:

  • compatible: Should be “lsi,zevio-gpio”
  • reg: Address and length of the register set for the device
  • #gpio-cells: Should be two. The first cell is the pin number and the
    second cell is used to specify optional parameters (currently unused).
  • gpio-controller: Marks the device node as a GPIO controller.

Example:
gpio: gpio@90000000 {
compatible = “lsi,zevio-gpio”;
reg = <0x90000000 0x1000>;
gpio-controller;
#gpio-cells = <2>;
};
