-+ *
-+ * ChangeLog
-+ *
-+ * 2004-09-05: Herbert Pötzl <herbert@13thfloor.at>
-+ * - added clock (de-)allocation code
-+ *
-+ * 2005-03-06: Arnaud Patard <arnaud.patard@rtp-net.org>
-+ * - h1940_ -> s3c2410 (this driver is now also used on the n30
-+ * machines :P)
-+ * - Debug messages are now enabled with the config option
-+ * TOUCHSCREEN_S3C2410_DEBUG
-+ * - Changed the way the value are read
-+ * - Input subsystem should now work
-+ * - Use ioremap and readl/writel
-+ *
-+ * 2005-03-23: Arnaud Patard <arnaud.patard@rtp-net.org>
-+ * - Make use of some undocumented features of the touchscreen
-+ * controller
