Jeff Garzik669a5db2006-08-29 18:12:40 -0400325 * hpt36x_init_one - Initialise an HPT366/368
326 * @dev: PCI device
327 * @id: Entry in match table
328 *
329 * Initialise an HPT36x device. There are some interesting complications
330 * here. Firstly the chip may report 366 and be one of several variants.
331 * Secondly all the timings depend on the clock for the chip which we must
332 * detect and look up
333 *
334 * This is the known chip mappings. It may be missing a couple of later
335 * releases.
336 *
337 * Chip version PCI Rev Notes
338 * HPT366 4 (HPT366) 0 UDMA66
339 * HPT366 4 (HPT366) 1 UDMA66
340 * HPT368 4 (HPT366) 2 UDMA66
341 * HPT37x/30x 4 (HPT366) 3+ Other driver
