  24 define KernelPackage/gpio-button-hotplug/description
  25  This is a replacement for the following in-kernel drivers:
  26  1) gpio_keys (KEYBOARD_GPIO)
  27  2) gpio_keys_polled (KEYBOARD_GPIO_POLLED)
  28
  29  Instead of generating input events (like in-kernel drivers do) it generates
  30  uevent-s and broadcasts them. This allows disabling input subsystem which is
  31  an overkill for OpenWrt simple needs.
