16 * Many thanks to Oliver Kuechemann for his support.
17 *
18 * ChangeLog:
19 * v0.1 - Initial release
20 * v0.2 - Hack to get around fake event 28's. (Bryan W. Headley)
21 * v0.3 - Make URB dynamic (Bryan W. Headley, Jun-8-2002)
22 * Released to Linux 2.4.19 and 2.5.x
23 * v0.4 - Rewrote substantial portions of the code to deal with
24 * corrected control sequences, timing, dynamic configuration,
25 * support of 6000U - 12000U, procfs, and macro key support
26 * (Jan-1-2003 - Feb-5-2003, Bryan W. Headley)
27 * v1.0 - Added support for diagnostic messages, count of messages
28 * received from URB - Mar-8-2003, Bryan W. Headley
29 * v1.1 - added support for tablet resolution, changed DV and proximity
30 * some corrections - Jun-22-2003, martin schneebacher
31 * - Added support for the sysfs interface, deprecating the
32 * procfs interface for 2.5.x kernel. Also added support for
33 * Wheel command. Bryan W. Headley July-15-2003.
34 * v1.2 - Reworked jitter timer as a kernel thread.
35 * Bryan W. Headley November-28-2003/Jan-10-2004.
36 * v1.3 - Repaired issue of kernel thread going nuts on single-processor
37 * machines, introduced programmableDelay as a command line
38 * parameter. Feb 7 2004, Bryan W. Headley.
39 * v1.4 - Re-wire jitter so it does not require a thread. Courtesy of
40 * Rene van Paassen. Added reporting of physical pointer device
41 * (e.g., stylus, mouse in reports 2, 3, 4, 5. We don't know
42 * for reports 1, 6.)
43 * what physical device reports for reports 1, 6.) Also enabled
44 * MOUSE and LENS tool button modes. Renamed "rubber" to "eraser".
45 * Feb 20, 2004, Bryan W. Headley.
46 * v1.5 - Added previousJitterable, so we don't do jitter delay when the
47 * user is holding a button down for periods of time.
48 *
49 * NOTE:
50 * This kernel driver is augmented by the "Aiptek" XFree86 input
51 * driver for your X server, as well as the Gaiptek GUI Front-end
52 * "Tablet Manager".
53 * These three products are highly interactive with one another,
54 * so therefore it's easier to document them all as one subsystem.
55 * Please visit the project's "home page", located at,
56 * http://aiptektablet.sourceforge.net.

368 * aiptek_irq can receive one of six potential reports.
369 * The documentation for each is in the body of the function.
370 *
371 * The tablet reports on several attributes per invocation of
372 * aiptek_irq. Because the Linux Input Event system allows the
373 * transmission of ONE attribute per input_report_xxx() call,
374 * collation has to be done on the other end to reconstitute
375 * a complete tablet report. Further, the number of Input Event reports
376 * submitted varies, depending on what USB report type, and circumstance.
377 * To deal with this, EV_MSC is used to indicate an 'end-of-report'
378 * message. This has been an undocumented convention understood by the kernel
379 * tablet driver and clients such as gpm and XFree86's tablet drivers.
380 *
381 * Of the information received from the tablet, the one piece I
382 * cannot transmit is the proximity bit (without resorting to an EV_MSC
383 * convention above.) I therefore have taken over REL_MISC and ABS_MISC
384 * (for relative and absolute reports, respectively) for communicating
385 * Proximity. Why two events? I thought it interesting to know if the
386 * Proximity event occurred while the tablet was in absolute or relative
387 * mode.
388 *
389 * Other tablets use the notion of a certain minimum stylus pressure
390 * to infer proximity. While that could have been done, that is yet
391 * another 'by convention' behavior, the documentation for which
392 * would be spread between two (or more) pieces of software.
393 *
394 * EV_MSC usage was terminated for this purpose in Linux 2.5.x, and
395 * replaced with the input_sync() method (which emits EV_SYN.)
