# Keymaps table
#
# This table creates an association between a keycode file and a kernel
# driver. It can be used to automatically override a keycode definition.
#
# Although not yet tested, it is mented to be added at udev.
#
# To use, you just need to run:
#	./ir-keytable -a
#
# Or, if the remote is not the first device:
#	./ir-keytable -a -s rc1		# for RC at rc1
#

# Format:
#	driver - name of the driver provided via uevent - use * for any driver
#	table -  RC keymap table, provided via uevent - use * for any table
#	file - file name. If directory is not specified, it will default to
#		/etc/rc_keymaps.
# For example:
# driver	table				file
# cx8800	*				./keycodes/rc5_hauppauge_new
# *		rc-avermedia-m135a-rm-jx	./keycodes/kworld_315u
# saa7134	rc-avermedia-m135a-rm-jx	./keycodes/keycodes/nec_terratec_cinergy_xs
# em28xx	*				./keycodes/kworld_315u
# *		*				./keycodes/rc5_hauppauge_new

# Table to automatically load the rc maps for the bundled IR's provided with the
# devices supported by the linux kernel

#driver table                    file
