1 | /* National Semiconductor NS87560UBD Super I/O controller used in |
2 | * HP [BCJ]x000 workstations. | |
3 | * | |
4 | * This chip is a horrid piece of engineering, and National | |
5 | * denies any knowledge of its existence. Thus no datasheet is | |
6 | * available off www.national.com. | |

25 | * Major changes to get basic interrupt infrastructure working to | |
26 | * hopefully be able to support all SuperIO devices. Currently | |
27 | * works with serial. -- John Marvin <jsm@fc.hp.com> | |

34 | /* NOTES: | |
35 | * | |
36 | * Function 0 is an IDE controller. It is identical to a PC87415 IDE | |
37 | * controller (and identifies itself as such). | |
38 | * | |
39 | * Function 1 is a "Legacy I/O" controller. Under this function is a | |
40 | * whole mess of legacy I/O peripherals. Of course, HP hasn't enabled | |
41 | * all the functionality in hardware, but the following is available: | |
42 | * | |
43 | * Two 16550A compatible serial controllers | |
44 | * An IEEE 1284 compatible parallel port | |
45 | * A floppy disk controller | |
46 | * | |
47 | * Function 2 is a USB controller. | |
48 | * | |
49 | * We must be incredibly careful during initialization. Since all | |
50 | * interrupts are routed through function 1 (which is not allowed by | |
51 | * the PCI spec), we need to program the PICs on the legacy I/O port | |
52 | * *before* we attempt to set up IDE and USB. @#$!& | |
53 | * | |
54 | * According to HP, devices are only enabled by firmware if they have | |
55 | * a physical device connected. | |
56 | * | |
57 | * Configuration register bits: | |
58 | * 0x5A: FDC, SP1, IDE1, SP2, IDE2, PAR, Reserved, P92 | |
59 | * 0x5B: RTC, 8259, 8254, DMA1, DMA2, KBC, P61, APM | |
60 | * | |
