Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+	  Say Y here if you want full HID support to connect keyboards,
+	  mice, joysticks, graphic tablets, or any other HID based devices
+	  to your computer via USB. You also need to select HID Input layer
+	  support (below) if you want to use keyboards, mice, joysticks and
+	  the like ... as well as Uninterruptible Power Supply (UPS) and
+	  monitor control devices.
+
+	  You can't use this driver and the HIDBP (Boot Protocol) keyboard
+	  and mouse drivers at the same time. More information is available:
+	  <file:Documentation/input/input.txt>.
+
+	  If unsure, say Y.
+

+ *
+ *  Many thanks to Oliver Kuechemann for his support.
+ *
+ *  ChangeLog:
+ *      v0.1 - Initial release
+ *      v0.2 - Hack to get around fake event 28's. (Bryan W. Headley)
+ *      v0.3 - Make URB dynamic (Bryan W. Headley, Jun-8-2002)
+ *             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.

+ * 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.

+ *  USB ATI Remote support
+ *
+ *  Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
+ *  Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
+ *
+ *  This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
+ *  porting to the 2.6 kernel interfaces, along with other modification 
+ *  to better match the style of the existing usb/input drivers.  However, the
+ *  protocol and hardware handling is essentially unchanged from 2.1.1.
+ *  
+ *  The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by 
+ *  Vojtech Pavlik.
+ *
+ *  Changes:
+ *
+ *  Feb 2004: Torrey Hoffman <thoffman@arnor.net>
+ *            Version 2.2.0
+ *  Jun 2004: Torrey Hoffman <thoffman@arnor.net>
+ *            Version 2.2.1
+ *            Added key repeat support contributed by:
+ *                Vincent Vanackere <vanackere@lif.univ-mrs.fr>
+ *            Added support for the "Lola" remote contributed by:
+ *                Seth Cohn <sethcohn@yahoo.com>

+ * Hardware & software notes
+ *
+ * These remote controls are distributed by ATI as part of their 
+ * "All-In-Wonder" video card packages.  The receiver self-identifies as a 
+ * "USB Receiver" with manufacturer "X10 Wireless Technology Inc".
+ *
+ * The "Lola" remote is available from X10.  See: 
+ *    http://www.x10.com/products/lola_sg1.htm
+ * The Lola is similar to the ATI remote but has no mouse support, and slightly
+ * different keys.
+ *
+ * It is possible to use multiple receivers and remotes on multiple computers 
+ * simultaneously by configuring them to use specific channels.
+ * 
+ * The RF protocol used by the remote supports 16 distinct channels, 1 to 16.  
+ * Actually, it may even support more, at least in some revisions of the 
+ * hardware.
+ *
+ * Each remote can be configured to transmit on one channel as follows:
+ *   - Press and hold the "hand icon" button.  
+ *   - When the red LED starts to blink, let go of the "hand icon" button. 
+ *   - When it stops blinking, input the channel code as two digits, from 01 
+ *     to 16, and press the hand icon again.
+ * 
+ * The timing can be a little tricky.  Try loading the module with debug=1
+ * to have the kernel print out messages about the remote control number
+ * and mask.  Note: debugging prints remote numbers as zero-based hexadecimal.
+ *
+ * The driver has a "channel_mask" parameter. This bitmask specifies which
+ * channels will be ignored by the module.  To mask out channels, just add 
+ * all the 2^channel_number values together.
+ *
+ * For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote
+ * ignore signals coming from remote controls transmitting on channel 4, but 
+ * accept all other channels.
+ *
+ * Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be 
+ * ignored.
+ *
+ * The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this 
+ * parameter are unused.

+ * Based upon original work by Radoslaw Garbacz (usb-support@ite.pl)
+ *  (http://freshmeat.net/projects/3mtouchscreendriver)
+ *
+ * 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 successfull tests with an EXII-5010UC
+ *
+ *  1.5 02/27/2005 ddstreet@ieee.org
+ *    Added module parameter to select raw or hw-calibrated coordinate reporting

+/*
+ * A driver for the Griffin Technology, Inc. "PowerMate" USB controller dial.
+ *
+ * v1.1, (c)2002 William R Sowerbutts <will@sowerbutts.com>
+ *
+ * This device is a anodised aluminium knob which connects over USB. It can measure
+ * clockwise and anticlockwise rotation. The dial also acts as a pushbutton with
+ * a spring for automatic release. The base contains a pair of LEDs which illuminate
+ * the translucent base. It rotates without limit and reports its relative rotation
+ * back to the host when polled by the USB controller.
+ *
+ * Testing with the knob I have has shown that it measures approximately 94 "clicks"
+ * for one full rotation. Testing with my High Speed Rotation Actuator (ok, it was 
+ * a variable speed cordless electric drill) has shown that the device can measure
+ * speeds of up to 7 clicks either clockwise or anticlockwise between pollings from
+ * the host. If it counts more than 7 clicks before it is polled, it will wrap back
+ * to zero and start counting again. This was at quite high speed, however, almost
+ * certainly faster than the human hand could turn it. Griffin say that it loses a
+ * pulse or two on a direction change; the granularity is so fine that I never
+ * noticed this in practice.
+ *
+ * The device's microcontroller can be programmed to set the LED to either a constant
+ * intensity, or to a rhythmic pulsing. Several patterns and speeds are available.
+ *
+ * Griffin were very happy to provide documentation and free hardware for development.
+ *
+ * Some userspace tools are available on the web: http://sowerbutts.com/powermate/

+ *  - fix "analog" buttons (reported as digital now)
+ *  - get rumble working
+ *
+ * History:
+ *
+ * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
+ *
+ * 2002-07-02 - 0.0.2 : basic working version
+ *  - all axes and 9 of the 10 buttons work (german InterAct device)
+ *  - the black button does not work
+ *
+ * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
+ *  - indentation fixes
+ *  - usb + input init sequence fixes
+ *
+ * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
+ *  - verified the lack of HID and report descriptors
+ *  - verified that ALL buttons WORK
+ *  - fixed d-pad to axes mapping
+ *
+ * 2002-07-17 - 0.0.5 : simplified d-pad handling
