+ * pata_via.c - VIA PATA for new ATA layer
+ * (C) 2005-2006 Red Hat Inc
+ * Alan Cox <alan@redhat.com>
+ *
+ * Documentation
+ * Most chipset documentation available under NDA only
+ *
+ * VIA version guide
+ * VIA VT82C561 - early design, uses ata_generic currently
+ * VIA VT82C576 - MWDMA, 33Mhz
+ * VIA VT82C586 - MWDMA, 33Mhz
+ * VIA VT82C586a - Added UDMA to 33Mhz
+ * VIA VT82C586b - UDMA33
+ * VIA VT82C596a - Nonfunctional UDMA66
+ * VIA VT82C596b - Working UDMA66
+ * VIA VT82C686 - Nonfunctional UDMA66
+ * VIA VT82C686a - Working UDMA66
+ * VIA VT82C686b - Updated to UDMA100
+ * VIA VT8231 - UDMA100
+ * VIA VT8233 - UDMA100
+ * VIA VT8233a - UDMA133
+ * VIA VT8233c - UDMA100
+ * VIA VT8235 - UDMA133
+ * VIA VT8237 - UDMA133
+ *
+ * Most registers remain compatible across chips. Others start reserved
+ * and acquire sensible semantics if set to 1 (eg cable detect). A few
+ * exceptions exist, notably around the FIFO settings.
+ *
+ * One additional quirk of the VIA design is that like ALi they use few
+ * PCI IDs for a lot of chips.
+ *
+ * Based heavily on:
+ *
+ * Version 3.38
+ *
+ * VIA IDE driver for Linux. Supported southbridges:
+ *
+ * vt82c576, vt82c586, vt82c586a, vt82c586b, vt82c596a, vt82c596b,
+ * vt82c686, vt82c686a, vt82c686b, vt8231, vt8233, vt8233c, vt8233a,
+ * vt8235, vt8237
