- * Kudos to ITM for providing me with the datasheet for the panel,

- * driver.
- *
- * It has meant that I've been able to correct my interpretation of the

- *
- * CC -- 2003/9/29
- *
- * History
- * 1.0 & 1.1 2003 (CC) vojtech@suse.cz
- * Original version for 2.4.x kernels
- *
- * 1.2 02/03/2005 (HCE) hc@mivu.no
- * Complete rewrite to support Linux 2.6.10, thanks to mtouchusb.c for hints.
- * Unfortunately no calibration support at this time.
- *
- * 1.2.1 09/03/2005 (HCE) hc@mivu.no
- * Code cleanup and adjusting syntax to start matching kernel standards
- *
- * 1.2.2 10/05/2006 (MJA) massad@gmail.com
- * Flag for detecting if the screen was being touch was incorrectly
- * inverted, so no touch events were being detected.

- *
- * History
- *
- * 0.3 & 0.4 2002 (TEJ) tejohnson@yahoo.com
- * Updated to 2.4.18, then 2.4.19
- * Old version still relied on stealing a minor
- *
- * 0.5 02/26/2004 (TEJ) tejohnson@yahoo.com
- * Complete rewrite using Linux Input in 2.6.3
- * Unfortunately no calibration support at this time
- *
- * 1.4 04/25/2004 (TEJ) tejohnson@yahoo.com
- * Changed reset from standard USB dev reset to vendor reset
- * Changed data sent to host from compensated to raw coordinates
- * Eliminated vendor/product module params
- * Performed multiple successful tests with an EXII-5010UC
- *
- * 1.5 02/27/2005 ddstreet@ieee.org
- * Added module parameter to select raw or hw-calibrated coordinate reporting
