   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 Gühring - pg@futureware.at - added the Device ID of the USB relais
  21  * from Rudolf Gugler

 307  * - BaudDivisor is a fixed point number encoded in a funny way.
 308  *   (--WRONG WAY OF THINKING--)
 309  *   BaudDivisor is a fixed point number encoded with following bit weighs:
 310  *   (-2)(-1)(13..0). It is a radical with a denominator of 4, so values
 311  *   end with 0.0 (00...), 0.25 (10...), 0.5 (01...), and 0.75 (11...).
 312  *   (--THE REALITY--)
 313  *   The both-bits-set has quite different meaning from 0.75 - the chip designers
 314  *   have decided it to mean 0.125 instead of 0.75.
 315  *   This info looked up in FTDI application note "FT8U232 DEVICES \ Data Rates
 316  *   and Flow Control Consideration for USB to RS232".
 317  * - BaudDivisor = (BaseClock / 16) / BaudRate, where the (=) operation should
 318  *   automagically re-encode the resulting value to take fractions into consideration.
 319  * As all values are integers, some bit twiddling is in order:
 320  *   BaudDivisor = (BaseClock / 16 / BaudRate) |
 321  *   (((BaseClock / 2 / BaudRate) & 4) ? 0x4000    // 0.5
 322  *    : ((BaseClock / 2 / BaudRate) & 2) ? 0x8000  // 0.25
 323  *    : ((BaseClock / 2 / BaudRate) & 1) ? 0xc000  // 0.125
 324  *    : 0)
 325  *
 326  * For the FT232BM, a 17th divisor bit was introduced to encode the multiples
 327  * of 0.125 missing from the FT8U232AM.  Bits 16 to 14 are coded as follows
 328  * (the first four codes are the same as for the FT8U232AM, where bit 16 is
 329  * always 0):
 330  *   000 - add .000 to divisor
 331  *   001 - add .500 to divisor
 332  *   010 - add .250 to divisor
 333  *   011 - add .125 to divisor
 334  *   100 - add .375 to divisor
 335  *   101 - add .625 to divisor
 336  *   110 - add .750 to divisor
 337  *   111 - add .875 to divisor
 338  * Bits 15 to 0 of the 17-bit divisor are placed in the urb value.  Bit 16 is
 339  * placed in bit 0 of the urb index.
 340  *
 341  * Note that there are a couple of special cases to support the highest baud
 342  * rates.  If the calculated divisor value is 1, this needs to be replaced with
 343  * 0.  Additionally for the FT232BM, if the calculated divisor value is 0x4001
 344  * (1.5), this needs to be replaced with 0x0001 (1) (but this divisor value is
 345  * not supported by the FT8U232AM).
