375 * SIIG serial cards have an PCI interface chip which also controls
376 * the UART clocking frequency. Each UART can be clocked independently
377 * (except cards equiped with 4 UARTs) and initial clocking settings
378 * are stored in the EEPROM chip. It can cause problems because this
379 * version of serial driver doesn't support differently clocked UART's
380 * on single PCI card. To prevent this, initialization functions set
381 * high frequency clocking for all UART's on given card. It is safe (I
382 * hope) because it doesn't touch EEPROM settings to prevent conflicts
383 * with other OSes (like M$ DOS).
384 *
385 * SIIG support added by Andrey Panin <pazke@donpac.ru>, 10/1999
386 *
387 * There is two family of SIIG serial cards with different PCI
388 * interface chip and different configuration methods:
389 * - 10x cards have control registers in IO and/or memory space;
390 * - 20x cards have control registers in standard PCI configuration space.
