/*
 * linux/drivers/char/dummy_keyb.c
 *
 * Allows CONFIG_VT on hardware without keyboards.

 *
 * What is this for?
 *
 * Not all systems have keyboards.  Some don't even have a keyboard
 * port.  However, some of those systems have video support and can
 * use the virtual terminal support for display.  However, the virtual
 * terminal code expects a keyboard of some kind.  This driver keeps
 * the virtual terminal code happy by providing it a "keyboard", albeit
 * a very quiet one.
 *
 * If you want to use the virtual terminal support but your system
 * does not support a keyboard, define CONFIG_DUMMY_KEYB along with
 * CONFIG_VT.
