173 + *
174 + * 2005-03-06: Arnaud Patard <arnaud.patard@rtp-net.org>
175 + * - h1940_ -> s3c2410 (this driver is now also used on the n30
176 + * machines :P)
177 + * - Debug messages are now enabled with the config option
178 + * TOUCHSCREEN_S3C2410_DEBUG
179 + * - Changed the way the value are read
180 + * - Input subsystem should now work
181 + * - Use ioremap and readl/writel
182 + *
183 + * 2005-03-23: Arnaud Patard <arnaud.patard@rtp-net.org>
184 + * - Make use of some undocumented features of the touchscreen
