2  * Definitions for the FTDI USB Single Port Serial Converter -
3  * known as FTDI_SIO (Serial Input/Output application of the chipset)
4  *
5  * The example I have is known as the USC-1000 which is available from
6  * http://www.dse.co.nz - cat no XH4214 It looks similar to this:
7  * http://www.dansdata.com/usbser.htm but I can't be sure There are other
8  * USC-1000s which don't look like my device though so beware!
9  *
10  * The device is based on the FTDI FT8U100AX chip. It has a DB25 on one side,
11  * USB on the other.
12  *
13  * Thanx to FTDI (http://www.ftdi.co.uk) for so kindly providing details
14  * of the protocol required to talk to the device and ongoing assistence
15  * during development.
16  *
17  * Bill Ryder - bryder@sgi.com formerly of Silicon Graphics, Inc.- wrote the
18  * FTDI_SIO implementation.
19  *
20  * Philipp G�hring - pg@futureware.at - added the Device ID of the USB relais
21  * from Rudolf Gugler

344  * The BaudDivisor values are calculated as follows:
345  * - BaseClock is either 12000000 or 48000000 depending on the device. FIXME: I wish
346  *   I knew how to detect old chips to select proper base clock!
347  * - BaudDivisor is a fixed point number encoded in a funny way.
348  *   (--WRONG WAY OF THINKING--)
349  *   BaudDivisor is a fixed point number encoded with following bit weighs:
350  *   (-2)(-1)(13..0). It is a radical with a denominator of 4, so values
351  *   end with 0.0 (00...), 0.25 (10...), 0.5 (01...), and 0.75 (11...).
352  *   (--THE REALITY--)
353  *   The both-bits-set has quite different meaning from 0.75 - the chip designers
354  *   have decided it to mean 0.125 instead of 0.75.
355  *   This info looked up in FTDI application note "FT8U232 DEVICES \ Data Rates
356  *   and Flow Control Consideration for USB to RS232".
357  * - BaudDivisor = (BaseClock / 16) / BaudRate, where the (=) operation should
358  *   automagically re-encode the resulting value to take fractions into consideration.
359  * As all values are integers, some bit twiddling is in order:
360  *   BaudDivisor = (BaseClock / 16 / BaudRate) |
361  *   (((BaseClock / 2 / BaudRate) & 4) ? 0x4000    // 0.5
362  *    : ((BaseClock / 2 / BaudRate) & 2) ? 0x8000  // 0.25
363  *    : ((BaseClock / 2 / BaudRate) & 1) ? 0xc000  // 0.125
364  *    : 0)
365  *
366  * For the FT232BM, a 17th divisor bit was introduced to encode the multiples
367  * of 0.125 missing from the FT8U232AM.  Bits 16 to 14 are coded as follows
368  * (the first four codes are the same as for the FT8U232AM, where bit 16 is
369  * always 0):
370  *   000 - add .000 to divisor
371  *   001 - add .500 to divisor
372  *   010 - add .250 to divisor
373  *   011 - add .125 to divisor
374  *   100 - add .375 to divisor
375  *   101 - add .625 to divisor
376  *   110 - add .750 to divisor
377  *   111 - add .875 to divisor
378  * Bits 15 to 0 of the 17-bit divisor are placed in the urb value.  Bit 16 is
379  * placed in bit 0 of the urb index.
380  *
381  * Note that there are a couple of special cases to support the highest baud
382  * rates.  If the calculated divisor value is 1, this needs to be replaced with
383  * 0.  Additionally for the FT232BM, if the calculated divisor value is 0x4001
384  * (1.5), this needs to be replaced with 0x0001 (1) (but this divisor value is
385  * not supported by the FT8U232AM).
