*
* See http://ftdi-usb-sio.sourceforge.net for upto date testing info
* and extra documentation
*
* (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:
* o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
* o 230400 at 12MHz
* so .. 8U232AM's baudrate setting codes are different
* - it has a two byte status code.
* - it returns characters every 16ms (the FTDI does it every 40ms)
*
* the bcdDevice value is used to differentiate FT232BM and FT245BM from
* the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
* combinations in both tables.
* FIXME: perhaps bcdDevice can also identify 12MHz devices, but I don't know
* if those ever went into mass production. [Ian Abbott]
