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

2746  * For example IER register on SBS, Inc. PMC-OctPro is located at
2747  * offset 0x10 from the UART base, while UART_IER is defined as 1
2748  * in include/linux/serial_reg.h,
