357 * version of serial driver doesn't support differently clocked UART's
358 * on single PCI card. To prevent this, initialization functions set
359 * high frequency clocking for all UART's on given card. It is safe (I

361 * with other OSes (like M$ DOS).
362 *
363 * SIIG support added by Andrey Panin <pazke@donpac.ru>, 10/1999

365 * There is two family of SIIG serial cards with different PCI
366 * interface chip and different configuration methods:
367 * - 10x cards have control registers in IO and/or memory space;
368 * - 20x cards have control registers in standard PCI configuration space.
369 *
370 * Note: all 10x cards have PCI device ids 0x10..
371 * all 20x cards have PCI device ids 0x20..
372 *
373 * There are also Quartet Serial cards which use Oxford Semiconductor
374 * 16954 quad UART PCI chip clocked by 18.432 MHz quartz.
