*
- * (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 transceiver 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 transceiver 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.
+ * Change entries from 2004 and earlier can be found in versions of this
+ * file in kernel versions prior to the 2.6.24 release.
