* See http://ftdi-usb-sio.sourceforge.net for upto date testing info
* and extra documentation
*
* (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
* 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.
* Switched from using spinlock to a semaphore, which fixes lots of problems.

* The logic involved in setting the baudrate can be cleanly split in 3 steps.
* Obtaining the actual baud rate is a little tricky since unix traditionally
* somehow ignored the possibility to set non-standard baud rates.
* 1. Standard baud rates are set in tty->termios->c_cflag
* 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
* replicated in nearly every serial driver you see.

* BmRequestType: 0100 0000B
* bRequest: FTDI_SIO_SET_BAUDRATE
* wValue: BaudRate value - see below
* wValue: BaudDivisor value - see below
* wIndex: Port
* wLength: 0
* Data: None
* The BaudDivisor values are calculated as follows:
* - BaseClock is either 12000000 or 48000000 depending on the device. FIXME: I wish
* I knew how to detect old chips to select proper base clock!
* - BaudDivisor is a fixed point number encoded in a funny way.
* (--WRONG WAY OF THINKING--)
* BaudDivisor is a fixed point number encoded with following bit weighs:
* (-2)(-1)(13..0). It is a radical with a denominator of 4, so values
* end with 0.0 (00...), 0.25 (10...), 0.5 (01...), and 0.75 (11...).
* (--THE REALITY--)
* The both-bits-set has quite different meaning from 0.75 - the chip designers
* have decided it to mean 0.125 instead of 0.75.
* This info looked up in FTDI application note "FT8U232 DEVICES \ Data Rates
* and Flow Control Consideration for USB to RS232".
* - BaudDivisor = (BaseClock / 16) / BaudRate, where the (=) operation should
* automagically re-encode the resulting value to take fractions into consideration.
* As all values are integers, some bit twiddling is in order:
* BaudDivisor = (BaseClock / 16 / BaudRate) |
* (((BaseClock / 2 / BaudRate) & 4) ? 0x4000 // 0.5
* : ((BaseClock / 2 / BaudRate) & 2) ? 0x8000 // 0.25
* : ((BaseClock / 2 / BaudRate) & 1) ? 0xc000 // 0.125
* : 0)
*
* For the FT232BM, a 17th divisor bit was introduced to encode the multiples
* of 0.125 missing from the FT8U232AM. Bits 16 to 14 are coded as follows
* (the first four codes are the same as for the FT8U232AM, where bit 16 is
* always 0):
* 000 - add .000 to divisor
* 001 - add .500 to divisor
* 010 - add .250 to divisor
* 011 - add .125 to divisor
* 100 - add .375 to divisor
* 101 - add .625 to divisor
* 110 - add .750 to divisor
* 111 - add .875 to divisor
* Bits 15 to 0 of the 17-bit divisor are placed in the urb value. Bit 16 is
* placed in bit 0 of the urb index.
*
* Note that there are a couple of special cases to support the highest baud
* rates. If the calculated divisor value is 1, this needs to be replaced with
* 0. Additionally for the FT232BM, if the calculated divisor value is 0x4001
* (1.5), this needs to be replaced with 0x0001 (1) (but this divisor value is
* not supported by the FT8U232AM).
