20 * (21/Jul/2004) Ian Abbott
21 * Incorporated Steven Turner's code to add support for the FT2232C chip.
22 * The prelimilary port to the 2.6 kernel was by Rus V. Brushkoff. I have
23 * fixed a couple of things.
25 * (27/May/2004) Ian Abbott
26 * Improved throttling code, mostly stolen from the WhiteHEAT driver.
28 * (26/Mar/2004) Jan Capek
29 * Added PID's for ICD-U20/ICD-U40 - incircuit PIC debuggers from CCS Inc.
31 * (09/Feb/2004) Ian Abbott
32 * Changed full name of USB-UIRT device to avoid "/" character.
33 * Added FTDI's alternate PID (0x6006) for FT232/245 devices.
34 * Added PID for "ELV USB Module UO100" from Stefan Frings.
36 * (21/Oct/2003) Ian Abbott
37 * Renamed some VID/PID macros for Matrix Orbital and Perle Systems
38 * devices. Removed Matrix Orbital and Perle Systems devices from the
39 * 8U232AM device table, but left them in the FT232BM table, as they are
40 * known to use only FT232BM.
42 * (17/Oct/2003) Scott Allen
43 * Added vid/pid for Perle Systems UltraPort USB serial converters
45 * (21/Sep/2003) Ian Abbott
46 * Added VID/PID for Omnidirectional Control Technology US101 USB to
47 * RS-232 adapter (also rebadged as Dick Smith Electronics XH6381).
48 * VID/PID supplied by Donald Gordon.
50 * (19/Aug/2003) Ian Abbott
51 * Freed urb's transfer buffer in write bulk callback.
52 * Omitted some paranoid checks in write bulk callback that don't matter.
53 * Scheduled work in write bulk callback regardless of port's open count.
55 * (05/Aug/2003) Ian Abbott
56 * Added VID/PID for ID TECH IDT1221U USB to RS-232 adapter.
57 * VID/PID provided by Steve Briggs.
59 * (23/Jul/2003) Ian Abbott
60 * Added PIDs for CrystalFontz 547, 633, 631, 635, 640 and 640 from
63 * (10/Jul/2003) David Glance
64 * Added PID for DSS-20 SyncStation cradle for Sony-Ericsson P800.
66 * (27/Jun/2003) Ian Abbott
67 * Reworked the urb handling logic. We have no more pool, but dynamically
68 * allocate the urb and the transfer buffer on the fly. In testing this
69 * does not incure any measurable overhead. This also relies on the fact
70 * that we have proper reference counting logic for urbs. I nicked this
71 * from Greg KH's Visor driver.
73 * (23/Jun/2003) Ian Abbott
74 * Reduced flip buffer pushes and corrected a data length test in
75 * ftdi_read_bulk_callback.
76 * Defererence pointers after any paranoid checks, not before.
78 * (21/Jun/2003) Erik Nygren
79 * Added support for Home Electronics Tira-1 IR transceiver using FT232BM chip.
80 * See <http://www.home-electro.com/tira1.htm>. Only operates properly
81 * at 100000 and RTS-CTS, so set custom divisor mode on startup.
82 * Also force the Tira-1 and USB-UIRT to only use their custom baud rates.
84 * (18/Jun/2003) Ian Abbott
85 * Added Device ID of the USB relais from Rudolf Gugler (backported from
86 * Philipp Gühring's patch for 2.5.x kernel).
87 * Moved read transfer buffer reallocation into startup function.
88 * Free existing write urb and transfer buffer in startup function.
89 * Only use urbs in write urb pool that were successfully allocated.
90 * Moved some constant macros out of functions.
91 * Minor whitespace and comment changes.
93 * (12/Jun/2003) David Norwood
94 * Added support for USB-UIRT IR transceiver using 8U232AM chip.
95 * See <http://home.earthlink.net/~jrhees/USBUIRT/index.htm>. Only
96 * operates properly at 312500, so set custom divisor mode on startup.
98 * (12/Jun/2003) Ian Abbott
99 * Added Sealevel SeaLINK+ 210x, 220x, 240x, 280x vid/pids from Tuan Hoang
100 * - I've eliminated some that don't seem to exist!
101 * Added Home Electronics Tira-1 IR transceiver pid from Chris Horn
102 * Some whitespace/coding-style cleanups
104 * (11/Jun/2003) Ian Abbott
105 * Fixed unsafe spinlock usage in ftdi_write
107 * (24/Feb/2003) Richard Shooter
108 * Increase read buffer size to improve read speeds at higher baud rates
109 * (specifically tested with up to 1Mb/sec at 1.5M baud)
111 * (23/Feb/2003) John Wilkins
112 * Added Xon/xoff flow control (activating support in the ftdi device)
113 * Added vid/pid for Videonetworks/Homechoice (UK ISP)
115 * (23/Feb/2003) Bill Ryder
116 * Added matrix orb device vid/pids from Wayne Wylupski
118 * (19/Feb/2003) Ian Abbott
119 * For TIOCSSERIAL, set alt_speed to 0 when ASYNC_SPD_MASK value has
120 * changed to something other than ASYNC_SPD_HI, ASYNC_SPD_VHI,
121 * ASYNC_SPD_SHI or ASYNC_SPD_WARP. Also, unless ASYNC_SPD_CUST is in
122 * force, don't bother changing baud rate when custom_divisor has changed.
124 * (18/Feb/2003) Ian Abbott
125 * Fixed TIOCMGET handling to include state of DTR and RTS, the state
126 * of which are now saved by set_dtr() and set_rts().
127 * Fixed improper storage class for buf in set_dtr() and set_rts().
128 * Added FT232BM chip type and support for its extra baud rates (compared
130 * Took account of special case divisor values for highest baud rates of
131 * FT8U232AM and FT232BM.
132 * For TIOCSSERIAL, forced alt_speed to 0 when ASYNC_SPD_CUST kludge used,
133 * as previous alt_speed setting is now stale.
134 * Moved startup code common between the startup routines for the
135 * different chip types into a common subroutine.
137 * (17/Feb/2003) Bill Ryder
138 * Added write urb buffer pool on a per device basis
139 * Added more checking for open file on callbacks (fixed OOPS)
140 * Added CrystalFontz 632 and 634 PIDs
141 * (thanx to CrystalFontz for the sample devices - they flushed out
143 * Minor debugging message changes
144 * Added throttle, unthrottle and chars_in_buffer functions
145 * Fixed FTDI_SIO (the original device) bug
146 * Fixed some shutdown handling
151 * (07/Jun/2002) Kuba Ober
152 * Changed FTDI_SIO_BASE_BAUD_TO_DIVISOR macro into ftdi_baud_to_divisor
153 * function. It was getting too complex.
154 * Fix the divisor calculation logic which was setting divisor of 0.125
155 * instead of 0.5 for fractional parts of divisor equal to 5/8, 6/8, 7/8.
156 * Also make it bump up the divisor to next integer in case of 7/8 - it's
157 * a better approximation.
159 * (25/Jul/2002) Bill Ryder inserted Dmitri's TIOCMIWAIT patch
160 * Not tested by me but it doesn't break anything I use.
162 * (04/Jan/2002) Kuba Ober
163 * Implemented 38400 baudrate kludge, where it can be substituted with other
164 * values. That's the only way to set custom baudrates.
165 * Implemented TIOCSSERIAL, TIOCGSERIAL ioctl's so that setserial is happy.
166 * FIXME: both baudrate things should eventually go to usbserial.c as other
167 * devices may need that functionality too. Actually, it can probably be
168 * merged in serial.c somehow - too many drivers repeat this code over
170 * Fixed baudrate forgetfulness - open() used to reset baudrate to 9600 every time.
171 * Divisors for baudrates are calculated by a macro.
172 * Small code cleanups. Ugly whitespace changes for Plato's sake only ;-].
174 * (04/Nov/2001) Bill Ryder
175 * Fixed bug in read_bulk_callback where incorrect urb buffer was used.
176 * Cleaned up write offset calculation
177 * Added write_room since default values can be incorrect for sio
178 * Changed write_bulk_callback to use same queue_task as other drivers
179 * (the previous version caused panics)
180 * Removed port iteration code since the device only has one I/O port and it
184 * Switched from using spinlock to a semaphore, which fixes lots of problems.
186 * (23/May/2001) Bill Ryder
187 * Added runtime debug patch (thanx Tyson D Sawyer).
188 * Cleaned up comments for 8U232
189 * Added parity, framing and overrun error handling
190 * Added receive break handling.
193 * Identify version on module load.
195 * (18/March/2001) Bill Ryder
197 * Added send break handling. (requires kernel patch too)
198 * Fixed 8U232AM hardware RTS/CTS etc status reporting.
199 * Added flipbuf fix copied from generic device
201 * (12/3/2000) Bill Ryder
202 * Added support for 8U232AM device.
203 * Moved PID and VIDs into header file only.
204 * Turned on low-latency for the tty (device will do high baudrates)
205 * Added shutdown routine to close files when device removed.
206 * More debug and error message cleanups.
208 * (11/13/2000) Bill Ryder
209 * Added spinlock protected open code and close code.
210 * Multiple opens work (sort of - see webpage mentioned above).
211 * Cleaned up comments. Removed multiple PID/VID definitions.
212 * Factorised cts/dtr code
213 * Made use of __FUNCTION__ in dbg's
215 * (11/01/2000) Adam J. Richter
216 * usb_device_id table support
219 * Fixed bug with urb->dev not being set properly, now that the usb
223 * Removed DEBUG #ifdefs with call to usb_serial_debug_data
226 * Added module_init and module_exit functions to handle the fact that this
227 * driver is a loadable module now.
229 * (04/04/2000) Bill Ryder
230 * Fixed bugs in TCGET/TCSET ioctls (by removing them - they are
231 * handled elsewhere in the tty io driver chain).
233 * (03/30/2000) Bill Ryder
234 * Implemented lots of ioctls
235 * Fixed a race condition in write
236 * Changed some dbg's to errs
239 * Split driver up into device specific pieces.

280 * The 8U232AM has the same API as the sio except for:
281 * - it can support MUCH higher baudrates; up to:
282 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
284 * so .. 8U232AM's baudrate setting codes are different
285 * - it has a two byte status code.
286 * - it returns characters every 16ms (the FTDI does it every 40ms)
288 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
289 * the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
290 * combinations in both tables.
291 * FIXME: perhaps bcdDevice can also identify 12MHz devices, but I don't know
292 * if those ever went into mass production. [Ian Abbott]

1053 * - set tty->termios->c_cflag speed to B38400
1054 * - set your real speed in tty->alt_speed; it gets ignored when
