2 * pata_via.c - VIA PATA for new ATA layer
3 * (C) 2005-2006 Red Hat Inc
6 * Most chipset documentation available under NDA only
9 * VIA VT82C561 - early design, uses ata_generic currently
10 * VIA VT82C576 - MWDMA, 33Mhz
11 * VIA VT82C586 - MWDMA, 33Mhz
12 * VIA VT82C586a - Added UDMA to 33Mhz
13 * VIA VT82C586b - UDMA33
14 * VIA VT82C596a - Nonfunctional UDMA66
15 * VIA VT82C596b - Working UDMA66
16 * VIA VT82C686 - Nonfunctional UDMA66
17 * VIA VT82C686a - Working UDMA66
18 * VIA VT82C686b - Updated to UDMA100
19 * VIA VT8231 - UDMA100
20 * VIA VT8233 - UDMA100
21 * VIA VT8233a - UDMA133
22 * VIA VT8233c - UDMA100
23 * VIA VT8235 - UDMA133
24 * VIA VT8237 - UDMA133
25 * VIA VT8237A - UDMA133
26 * VIA VT8237S - UDMA133
27 * VIA VT8251 - UDMA133
29 * Most registers remain compatible across chips. Others start reserved
30 * and acquire sensible semantics if set to 1 (eg cable detect). A few
31 * exceptions exist, notably around the FIFO settings.
33 * One additional quirk of the VIA design is that like ALi they use few
34 * PCI IDs for a lot of chips.
40 * VIA IDE driver for Linux. Supported southbridges:
