4622761326 Enable workaround for isapnp assigning already used interrupts to pnp 
cards by masking them out with a "options ISAPNP_ALLOC_INTR_MASK=..."
in kernel config.

77274e73c6 Add a `variant number' to the tables, so we can handle slight variations in 
the chipset without doing something substantially more gross.

fd400e0ddc Add a kluge to ignore I/O and memory ranges with a size of zero, so we don't 
blow up in bus_space_{map,unmap}().  At least one card uses this to `disable'
a logical device.
(XXX There's probably a better way to do this.)

ddb8209b40 XXX Add a disgusting hack to make the CS sound chips work in PnP mode. 
XXX Read about it in isapnp.c.

c312dc3f08 Avoid looping forever with cards that can only use one I/O address, 
and specify a 0 alignment.

5599443810 If ISA DMA is not present in the kernel (i.e. no ISA DMA-using devices 
configured in), don't call ISA DMA functions to check for DRQs being
free.  Just return EINVAL in this case.  Fixes PR #6187, from Herb Peyerl.

bdb2269a46 Create a master list of pnp logical and compatibility device codes instead 
of hard-coding it into each driver and use a centralized probe function.

6ea0ab26e2 Don't reference functions defined in isadma.c if we don't have to, 
since we might not have any ISA DMA-using devices configured, thus
isadma.c won't be compiled.  Fixes a problem reported by Kevin Lahey.

Also, since there are only 8 DMA channels, don't bother checking
DRQs 8 - 15.

c12bf4cc9f DTRT with level and edge interrupts: 
- add a type field to the isapnp_pin struct and set to IST_EDGE or
      IST_LEVEL depending on the card configuration data.
    - use the irq type field in all the drivers instead of hardcoding it.

2fe3b9727a - increase string space for device class names 
- fix the parser so that non-compliant isapnp devices work, and we
  give up when there are too many errors (some on-board pnp sound/atapi/game
  soundblaster compatible card).  reported by chuck cranor
- fix the parser so that configuration tags that come after the
  end-dependencies tag or before the begin-dependencies tag are merged
  in properly (gravis ultrasound). reported by gary duzan
  We now build a tree of card -> logical-dev -> conf, and in the end we
  convert it to a list of conf...
