* (kernel 2.5.x variant, June-14-2002) * Released to Linux 2.4.19 and 2.5.x
*/ * v0.4 - Rewrote substantial portions of the code to deal with
* corrected control sequences, timing, dynamic configuration,
/* * support of 6000U - 12000U, procfs, and macro key support
* (Jan-1-2003 - Feb-5-2003, Bryan W. Headley)
* v1.0 - Added support for diagnostic messages, count of messages
* received from URB - Mar-8-2003, Bryan W. Headley
* v1.1 - added support for tablet resolution, changed DV and proximity
* some corrections - Jun-22-2003, martin schneebacher
* - Added support for the sysfs interface, deprecating the
* procfs interface for 2.5.x kernel. Also added support for
* Wheel command. Bryan W. Headley July-15-2003.
* v1.2 - Reworked jitter timer as a kernel thread.
* Bryan W. Headley November-28-2003/Jan-10-2004.
* v1.3 - Repaired issue of kernel thread going nuts on single-processor
* machines, introduced programmableDelay as a command line
* parameter. Feb 7 2004, Bryan W. Headley.
* v1.4 - Re-wire jitter so it does not require a thread. Courtesy of
* Rene van Paassen. Added reporting of physical pointer device
* (e.g., stylus, mouse in reports 2, 3, 4, 5. We don't know
* for reports 1, 6.)
* what physical device reports for reports 1, 6.) Also enabled
* MOUSE and LENS tool button modes. Renamed "rubber" to "eraser".
* Feb 20, 2004, Bryan W. Headley.
* v1.5 - Added previousJitterable, so we don't do jitter delay when the
* user is holding a button down for periods of time.
*
* NOTE:
* This kernel driver is augmented by the "Aiptek" XFree86 input
* driver for your X server, as well as the Gaiptek GUI Front-end
* "Tablet Manager".
* These three products are highly interactive with one another,
* so therefore it's easier to document them all as one subsystem.
* Please visit the project's "home page", located at,
* http://aiptektablet.sourceforge.net.

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