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