18 * Based upon original work by Chris Collins <xfire-itmtouch@xware.cx>.
19 *
20 * Kudos to ITM for providing me with the datasheet for the panel,
21 * even though it was a day later than I had finished writing this
22 * driver.
23 *
24 * It has meant that I've been able to correct my interpretation of the
25 * protocol packets however.

27 * CC -- 2003/9/29
28 *
29 * History
30 * 1.0 & 1.1 2003 (CC) vojtech@suse.cz
31 * Original version for 2.4.x kernels
32 *
33 * 1.2 02/03/2005 (HCE) hc@mivu.no
34 * Complete rewrite to support Linux 2.6.10, thanks to mtouchusb.c for hints.
35 * Unfortunately no calibration support at this time.
36 *
37 * 1.2.1 09/03/2005 (HCE) hc@mivu.no
38 * Code cleanup and adjusting syntax to start matching kernel standards
39 *
40 * 1.2.2 10/05/2006 (MJA) massad@gmail.com
41 * Flag for detecting if the screen was being touch was incorrectly
42 * inverted, so no touch events were being detected.

23 * 0.3 & 0.4 2002 (TEJ) tejohnson@yahoo.com

26 *
27 * 0.5 02/26/2004 (TEJ) tejohnson@yahoo.com

31 * 1.4 04/25/2004 (TEJ) tejohnson@yahoo.com
32 * Changed reset from standard USB dev reset to vendor reset
33 * Changed data sent to host from compensated to raw coordinates
34 * Eliminated vendor/product module params
35 * Performed multiple successful tests with an EXII-5010UC
36 *
37 * 1.5 02/27/2005 ddstreet@ieee.org
38 * Added module parameter to select raw or hw-calibrated coordinate reporting
