bridge between OLDCARD and NEWCARD for drivers to inquire after the
function number (eg, 0, 1, 2). Nobody ever used it, so retire it
with honors. NEWCARD never implemented it, and the same information
can be obtained by the pccard_get_function_number().

Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.
Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.
Free approx 86 major numbers with a mostly automatically generated patch.
A number of strategic drivers have been left behind by caution, and a few
because they still (ab)use their major number.
thread being waken up. The thread waken up can run at a priority as
high as after tsleep().
- Replace selwakeup()s with selwakeuppri()s and pass appropriate
priorities.
- Add cv_broadcastpri() which raises the priority of the broadcast
threads. Used by selwakeuppri() if collision occurs.
Not objected in: -arch, -current
2. Include backwards compatibility good for the moment (eventually will
be turned off in current, but allow for a short transition period).

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.
This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

o Update copyright.
o Add a tunable to allow the ti12xx to initialize the pci clock. Some rare
cards need it.
o rename 67xx -> 6729 since there's really only one chip in this family.
o from pcic_pci_pd6729_init call the routing code
o Fix some comments out routing on the TI-1130 class (1030, 1130 and 1131)
MFC: After RE@ says it is ok.
Fix a bug with the 3.3V code for the ricoh bridges. I got the bit
detect backwards. Also, we can only detect 3.3V cards when the GPI
interrupt is disabled. So when it is enabled assume 5.0V card.

to MAX-1 -> 0. This should allow for less potential for conflict
between pccardd/pccardc and drivers. As far as I can tell no drivers
try to use window 4, so this should be a no-op for them.
o reduce the extra-long ID names.
o TI-1510, 1520 and 4510 support.
o MFUNC is the name of the register on TI 1200 and newer chips (except
125x and 1450). Initialize it in the func routine, but only
if NO_MFUNC isn't set.
o better comments about above workaround
o register definitions for MFUNC.
o move zoom video disable to a better place.
the slot info. This brings OLDCARD's API much closer to NEWCARD and
will allow moving more information into the kernel from pccard.conf
for common drivers (ed).
windows. Right now we only support pci chips that are memory mapped.
These are the most common bridges in use today and will help a large
majority of the users.
I/O mapped PCI chips support this functionality in a different way, as
do some of the ISA bridges (but only when mounted on a motherboard).
These chips are not supported by this change.
This allows one to select the method of 3.3V card detection from the
three possible choices (none (0), the "6710 way" (1) and the "6729
way" (2)). The default is the 6710 way, since it works in the most
cases. The datasheets for the 6722 suggest that the '29 way is more
correct, but experience has shown this method to cause some laptops to
hang solid. See source code for details until I update the man page.

o It needs to have pcic_isa_intr intrrupt handler
o for pci interrupts, in the func interrupt handler it needs to check the isa
registers rather than the pci ones for card present.
o better commentary for some of the strangeness of the 6729 on pci
o fix some crunchy comments to better reflect reality.
With this I almost have the WL200 working, but an interrupt storm
after attach is causing problems for reasons unknown. This code
doesn't seem to break the normal clpd6729 case, and I'd like others
with 6729 cards to try to test it (there were some that were used for
external pccard slots in pci only systems).
o Add preliminary support for Cirrus Logic CL-PD6729 using PCI
interrupts. To use it you you need to set hw.pcic.pd6729_intr_path
to 2. This is allow us to still default to ISA intrrupt path for
this part (which is found much more often in laptops using ISA IRQs).
But some PCI cards have this part on them and this should allow them
to be used. It is untested on PCI, but it seems to not break the ISA
case.
o Better sysctl descriptions (I hope).
that's binary compatible for -stable. While binary compatibility doesn't
matter much in -current, it is critical for -stable. This change requires
pccardd/pccardc to be recompiled.
bridges in modern hardware (that hardware w/ lots of RAM). Raise the
address from 0x44000000 to 0x88000000 to match what we do with
NEWCARD. However, this really should be done in the pci layer.
o ToPIC is happy with two cards now, even when the two cards are
modems.
o Fix (all?) hangs on boot when power is applied to the card. I
suspect that this will make the Ricoh bridges happier and also
make a lot of VAIO owners happy (confirm to me in private email
please :-).
o All Cardbus bridges should now support 3.3V, X.XV and Y.YV cards,
to the extent that the underlying hardware supports such cards.
(X.X and Y.Y haven't been assigned values yet :-).
o Better 3.3V support for Ricoh ISA bridges.
How:
o Don't mess with the power register when scanning the cards. It
is unnecessary and causes BADVcc conditions on many chipsets. These
in turn can cause an interrupt storm.
o Make pcic_disable reset the slot's voltage.
o Move initializing voltage for the slot until after it has been
disabled.
o Fix a lot of issues with the pcic_cardbus_power routine. We
now properly enable the card and take it out of reset after
a power change.
o When detecting the card's voltage, if we're in a BadVcc state,
direct the bridge to rescan the card for what it supports.
(we might need to in the future set the power register to 0
before doing this).
o Don't preserve CLKSTOP. need to revisit this.
o Better support for Ricoh ISA bridges for 3.3V cards.
o Don't write to PCIC_POWER directly as offten, but instead go
through the pcic_power interface.
o All cardbus bridges now default to use cardbus power control.
o Add misc register definitions.
o remove some (now) bogus comments.
