* SIIG serial cards have an PCI interface chip which also controls

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