7 *
8 * Thanks to HighPoint Technologies for their assistance, and hardware.
9 * Special Thanks to Jon Burchmore in SanDiego for the deep pockets, his
10 * donation of an ABit BP6 mainboard, processor, and memory acellerated
11 * development and support.
12 *
13 * Note that final HPT370 support was done by force extraction of GPL.
14 *
15 * - add function for getting/setting power status of drive
16 * - the HPT370's state machine can get confused. reset it before each dma
17 * xfer to prevent that from happening.
18 * - reset state engine whenever we get an error.
19 * - check for busmaster state at end of dma.
20 * - use new highpoint timings.
21 * - detect bus speed using highpoint register.
22 * - use pll if we don't have a clock table. added a 66MHz table that's
23 * just 2x the 33MHz table.
24 * - removed turnaround. NOTE: we never want to switch between pll and
25 * pci clocks as the chip can glitch in those cases. the highpoint
26 * approved workaround slows everything down too much to be useful. in
27 * addition, we would have to serialize access to each chip.
28 * Adrian Sun <a.sun@sun.com>
29 *
30 * add drive timings for 66MHz PCI bus,
31 * fix ATA Cable signal detection, fix incorrect /proc info
32 * add /proc display for per-drive PIO/DMA/UDMA mode and
33 * per-channel ATA-33/66 Cable detect.
34 * Duncan Laurie <void@sun.com>
35 *
36 * fixup /proc output for multiple controllers
37 * Tim Hockin <thockin@sun.com>
38 *
39 * On hpt366:
40 * Reset the hpt366 on error, reset on dma
41 * Fix disabling Fast Interrupt hpt366.
42 * Mike Waychison <crlf@sun.com>
43 *
44 * Added support for 372N clocking and clock switching. The 372N needs
45 * different clocks on read/write. This requires overloading rw_disk and
46 * other deeply crazy things. Thanks to <http://www.hoerstreich.de> for
47 * keeping me sane.
48 * Alan Cox <alan@redhat.com>
