438  * SIIG serial cards have an PCI interface chip which also controls
439  * the UART clocking frequency. Each UART can be clocked independently
440  * (except cards equipped with 4 UARTs) and initial clocking settings
441  * are stored in the EEPROM chip. It can cause problems because this
442  * version of serial driver doesn't support differently clocked UART's
443  * on single PCI card. To prevent this, initialization functions set
444  * high frequency clocking for all UART's on given card. It is safe (I
445  * hope) because it doesn't touch EEPROM settings to prevent conflicts
446  * with other OSes (like M$ DOS).
447  *
448  *  SIIG support added by Andrey Panin <pazke@donpac.ru>, 10/1999
449  *
450  * There is two family of SIIG serial cards with different PCI
451  * interface chip and different configuration methods:
452  *     - 10x cards have control registers in IO and/or memory space;
453  *     - 20x cards have control registers in standard PCI configuration space.
454  *
455  * Note: all 10x cards have PCI device ids 0x10..
456  *       all 20x cards have PCI device ids 0x20..
457  *
458  * There are also Quartet Serial cards which use Oxford Semiconductor
459  * 16954 quad UART PCI chip clocked by 18.432 MHz quartz.
460  *
461  * Note: some SIIG cards are probed by the parport_serial object.
