Jeff Garzik669a5db2006-08-29 18:12:40 -0400370 * hpt36x_init_one - Initialise an HPT366/368
371 * @dev: PCI device
372 * @id: Entry in match table
373 *
374 * Initialise an HPT36x device. There are some interesting complications
375 * here. Firstly the chip may report 366 and be one of several variants.
376 * Secondly all the timings depend on the clock for the chip which we must
377 * detect and look up
378 *
379 * This is the known chip mappings. It may be missing a couple of later
380 * releases.
381 *
382 * Chip version PCI Rev Notes
383 * HPT366 4 (HPT366) 0 UDMA66
384 * HPT366 4 (HPT366) 1 UDMA66
385 * HPT368 4 (HPT366) 2 UDMA66
386 * HPT37x/30x 4 (HPT366) 3+ Other driver
