/*
 * SIIG serial cards have an PCI interface chip which also controls
 * the UART clocking frequency. Each UART can be clocked independently
 * (except cards equiped 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.
