2 * pata_optidma.c - Opti DMA PATA for new ATA layer
3 * (C) 2006 Red Hat Inc
Jeff Garzik669a5db2006-08-29 18:12:40 -04004 *
5 * The Opti DMA controllers are related to the older PIO PCI controllers
6 * and indeed the VLB ones. The main differences are that the timing
7 * numbers are now based off PCI clocks not VLB and differ, and that
8 * MWDMA is supported.
9 *
10 * This driver should support Viper-N+, FireStar, FireStar Plus.
11 *
12 * These devices support virtual DMA for read (aka the CS5520). Later
13 * chips support UDMA33, but only if the rest of the board logic does,
14 * so you have to get this right. We don't support the virtual DMA
15 * but we do handle UDMA.
16 *
17 * Bits that are worth knowing
18 * Most control registers are shadowed into I/O registers
19 * 0x1F5 bit 0 tells you if the PCI/VLB clock is 33 or 25Mhz
20 * Virtual DMA registers *move* between rev 0x02 and rev 0x10
21 * UDMA requires a 66MHz FSB
22 *
