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!

+ *
+ * (21/Jul/2004) Ian Abbott
+ * Incorporated Steven Turner's code to add support for the FT2232C chip.
+ * The prelimilary port to the 2.6 kernel was by Rus V. Brushkoff. I have
+ * fixed a couple of things.
+ *
+ * (27/May/2004) Ian Abbott
+ * Improved throttling code, mostly stolen from the WhiteHEAT driver.
+ *
+ * (26/Mar/2004) Jan Capek
+ * Added PID's for ICD-U20/ICD-U40 - incircuit PIC debuggers from CCS Inc.
+ *
+ * (09/Feb/2004) Ian Abbott
+ * Changed full name of USB-UIRT device to avoid "/" character.
+ * Added FTDI's alternate PID (0x6006) for FT232/245 devices.
+ * Added PID for "ELV USB Module UO100" from Stefan Frings.
+ *
+ * (21/Oct/2003) Ian Abbott
+ * Renamed some VID/PID macros for Matrix Orbital and Perle Systems
+ * devices. Removed Matrix Orbital and Perle Systems devices from the
+ * 8U232AM device table, but left them in the FT232BM table, as they are
+ * known to use only FT232BM.
+ *
+ * (17/Oct/2003) Scott Allen
+ * Added vid/pid for Perle Systems UltraPort USB serial converters
+ *
+ * (21/Sep/2003) Ian Abbott
+ * Added VID/PID for Omnidirectional Control Technology US101 USB to
+ * RS-232 adapter (also rebadged as Dick Smith Electronics XH6381).
+ * VID/PID supplied by Donald Gordon.
+ *
+ * (19/Aug/2003) Ian Abbott
+ * Freed urb's transfer buffer in write bulk callback.
+ * Omitted some paranoid checks in write bulk callback that don't matter.
+ * Scheduled work in write bulk callback regardless of port's open count.
+ *
+ * (05/Aug/2003) Ian Abbott
+ * Added VID/PID for ID TECH IDT1221U USB to RS-232 adapter.
+ * VID/PID provided by Steve Briggs.
+ *
+ * (23/Jul/2003) Ian Abbott
+ * Added PIDs for CrystalFontz 547, 633, 631, 635, 640 and 640 from
+ * Wayne Wylupski.
+ *
+ * (10/Jul/2003) David Glance
+ * Added PID for DSS-20 SyncStation cradle for Sony-Ericsson P800.
+ *
+ * (27/Jun/2003) Ian Abbott
+ * Reworked the urb handling logic. We have no more pool, but dynamically
+ * allocate the urb and the transfer buffer on the fly. In testing this
+ * does not incure any measurable overhead. This also relies on the fact
+ * that we have proper reference counting logic for urbs. I nicked this
+ * from Greg KH's Visor driver.
+ *
+ * (23/Jun/2003) Ian Abbott
+ * Reduced flip buffer pushes and corrected a data length test in
+ * ftdi_read_bulk_callback.
+ * Defererence pointers after any paranoid checks, not before.
+ *
+ * (21/Jun/2003) Erik Nygren
+ * Added support for Home Electronics Tira-1 IR tranceiver using FT232BM chip.
+ * See <http://www.home-electro.com/tira1.htm>. Only operates properly
+ * at 100000 and RTS-CTS, so set custom divisor mode on startup.
+ * Also force the Tira-1 and USB-UIRT to only use their custom baud rates.
+ *
+ * (18/Jun/2003) Ian Abbott
+ * Added Device ID of the USB relais from Rudolf Gugler (backported from
+ * Philipp Gühring's patch for 2.5.x kernel).
+ * Moved read transfer buffer reallocation into startup function.
+ * Free existing write urb and transfer buffer in startup function.
+ * Only use urbs in write urb pool that were successfully allocated.
+ * Moved some constant macros out of functions.
+ * Minor whitespace and comment changes.
+ *
+ * (12/Jun/2003) David Norwood
+ * Added support for USB-UIRT IR tranceiver using 8U232AM chip.
+ * See <http://home.earthlink.net/~jrhees/USBUIRT/index.htm>. Only
+ * operates properly at 312500, so set custom divisor mode on startup.
+ *
+ * (12/Jun/2003) Ian Abbott
+ * Added Sealevel SeaLINK+ 210x, 220x, 240x, 280x vid/pids from Tuan Hoang
+ * - I've eliminated some that don't seem to exist!
+ * Added Home Electronics Tira-1 IR transceiver pid from Chris Horn
+ * Some whitespace/coding-style cleanups
+ *
+ * (11/Jun/2003) Ian Abbott
+ * Fixed unsafe spinlock usage in ftdi_write
+ *
+ * (24/Feb/2003) Richard Shooter
+ * Increase read buffer size to improve read speeds at higher baud rates
+ * (specifically tested with up to 1Mb/sec at 1.5M baud)
+ *
+ * (23/Feb/2003) John Wilkins
+ * Added Xon/xoff flow control (activating support in the ftdi device)
+ * Added vid/pid for Videonetworks/Homechoice (UK ISP)
+ *
+ * (23/Feb/2003) Bill Ryder
+ * Added matrix orb device vid/pids from Wayne Wylupski
+ *
+ * (19/Feb/2003) Ian Abbott
+ * For TIOCSSERIAL, set alt_speed to 0 when ASYNC_SPD_MASK value has
+ * changed to something other than ASYNC_SPD_HI, ASYNC_SPD_VHI,
+ * ASYNC_SPD_SHI or ASYNC_SPD_WARP. Also, unless ASYNC_SPD_CUST is in
+ * force, don't bother changing baud rate when custom_divisor has changed.
+ *
+ * (18/Feb/2003) Ian Abbott
+ * Fixed TIOCMGET handling to include state of DTR and RTS, the state
+ * of which are now saved by set_dtr() and set_rts().
+ * Fixed improper storage class for buf in set_dtr() and set_rts().
+ * Added FT232BM chip type and support for its extra baud rates (compared
+ * to FT8U232AM).
+ * Took account of special case divisor values for highest baud rates of
+ * FT8U232AM and FT232BM.
+ * For TIOCSSERIAL, forced alt_speed to 0 when ASYNC_SPD_CUST kludge used,
+ * as previous alt_speed setting is now stale.
+ * Moved startup code common between the startup routines for the
+ * different chip types into a common subroutine.
+ *
+ * (17/Feb/2003) Bill Ryder
+ * Added write urb buffer pool on a per device basis
+ * Added more checking for open file on callbacks (fixed OOPS)
+ * Added CrystalFontz 632 and 634 PIDs
+ * (thanx to CrystalFontz for the sample devices - they flushed out
+ * some driver bugs)
+ * Minor debugging message changes
+ * Added throttle, unthrottle and chars_in_buffer functions
+ * Fixed FTDI_SIO (the original device) bug
+ * Fixed some shutdown handling
+ *
+ *
+ *
+ *
+ * (07/Jun/2002) Kuba Ober
+ * Changed FTDI_SIO_BASE_BAUD_TO_DIVISOR macro into ftdi_baud_to_divisor
+ * function. It was getting too complex.
+ * Fix the divisor calculation logic which was setting divisor of 0.125
+ * instead of 0.5 for fractional parts of divisor equal to 5/8, 6/8, 7/8.
+ * Also make it bump up the divisor to next integer in case of 7/8 - it's
+ * a better approximation.
+ *
+ * (25/Jul/2002) Bill Ryder inserted Dmitri's TIOCMIWAIT patch
+ * Not tested by me but it doesn't break anything I use.
+ *
+ * (04/Jan/2002) Kuba Ober
+ * Implemented 38400 baudrate kludge, where it can be substituted with other
+ * values. That's the only way to set custom baudrates.
+ * Implemented TIOCSSERIAL, TIOCGSERIAL ioctl's so that setserial is happy.
+ * FIXME: both baudrate things should eventually go to usbserial.c as other
+ * devices may need that functionality too. Actually, it can probably be
+ * merged in serial.c somehow - too many drivers repeat this code over
+ * and over.
+ * Fixed baudrate forgetfulness - open() used to reset baudrate to 9600 every time.
+ * Divisors for baudrates are calculated by a macro.
+ * Small code cleanups. Ugly whitespace changes for Plato's sake only ;-].
+ *
+ * (04/Nov/2001) Bill Ryder
+ * Fixed bug in read_bulk_callback where incorrect urb buffer was used.
+ * Cleaned up write offset calculation
+ * Added write_room since default values can be incorrect for sio
+ * Changed write_bulk_callback to use same queue_task as other drivers
+ * (the previous version caused panics)
+ * Removed port iteration code since the device only has one I/O port and it
+ * was wrong anyway.
+ *
+ * (31/May/2001) gkh
+ * Switched from using spinlock to a semaphore, which fixes lots of problems.
+ *
+ * (23/May/2001) Bill Ryder
+ * Added runtime debug patch (thanx Tyson D Sawyer).
+ * Cleaned up comments for 8U232
+ * Added parity, framing and overrun error handling
+ * Added receive break handling.
+ *
+ * (04/08/2001) gb
+ * Identify version on module load.
+ *
+ * (18/March/2001) Bill Ryder
+ * (Not released)
+ * Added send break handling. (requires kernel patch too)
+ * Fixed 8U232AM hardware RTS/CTS etc status reporting.
+ * Added flipbuf fix copied from generic device
+ *
+ * (12/3/2000) Bill Ryder
+ * Added support for 8U232AM device.
+ * Moved PID and VIDs into header file only.
+ * Turned on low-latency for the tty (device will do high baudrates)
+ * Added shutdown routine to close files when device removed.
+ * More debug and error message cleanups.
+ *
+ * (11/13/2000) Bill Ryder
+ * Added spinlock protected open code and close code.
+ * Multiple opens work (sort of - see webpage mentioned above).
+ * Cleaned up comments. Removed multiple PID/VID definitions.
+ * Factorised cts/dtr code
+ * Made use of __FUNCTION__ in dbg's
+ *
+ * (11/01/2000) Adam J. Richter
+ * usb_device_id table support
+ *
+ * (10/05/2000) gkh
+ * Fixed bug with urb->dev not being set properly, now that the usb
+ * core needs it.
+ *
+ * (09/11/2000) gkh
+ * Removed DEBUG #ifdefs with call to usb_serial_debug_data
+ *
+ * (07/19/2000) gkh
+ * Added module_init and module_exit functions to handle the fact that this
+ * driver is a loadable module now.
+ *
+ * (04/04/2000) Bill Ryder
+ * Fixed bugs in TCGET/TCSET ioctls (by removing them - they are
+ * handled elsewhere in the tty io driver chain).
+ *
+ * (03/30/2000) Bill Ryder
+ * Implemented lots of ioctls
+ * Fixed a race condition in write
+ * Changed some dbg's to errs
+ *
+ * (03/26/2000) gkh
+ * Split driver up into device specific pieces.

+ * The 8U232AM has the same API as the sio except for:
+ * - it can support MUCH higher baudrates; up to:

+ * 2. If these are not enough, you can set any speed using alt_speed as follows:
+ * - set tty->termios->c_cflag speed to B38400
+ * - set your real speed in tty->alt_speed; it gets ignored when
+ * alt_speed==0, (or)
+ * - call TIOCSSERIAL ioctl with (struct serial_struct) set as follows:
+ * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP], this just
+ * sets alt_speed to (HI: 57600, VHI: 115200, SHI: 230400, WARP: 460800)
+ * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
+ * 3. You can also set baud rate by setting custom divisor as follows
+ * - set tty->termios->c_cflag speed to B38400
+ * - call TIOCSSERIAL ioctl with (struct serial_struct) set as follows:
+ * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
+ * o custom_divisor set to baud_base / your_new_baudrate
+ * ** Step 3 is done courtesy of code borrowed from serial.c - I should really
+ * spend some time and separate+move this common code to serial.c, it is
