 1.17  20-Dec-2023  thorpej Remove unnecessary <sys/malloc.h>.
 1.16  22-Jan-2022  thorpej Change the devhandle_from_*() functions to also take a "super handle",
from which the newly created handle will inherit it's implementation.
The root implementation for a new handle type is used if an invalid
"super handle" is passed.
 1.15  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.14  24-Apr-2021  thorpej branches: 1.14.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).
 1.13  05-Mar-2021  rin branches: 1.13.2;
Convert to intr_establish_xname().
 1.12  27-Oct-2012  chs branches: 1.12.50;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.11  30-Jun-2011  matt branches: 1.11.2; 1.11.12;
Modify mapiodev to take a third argument indicating whether the space
should be prefetchable (true) or not (false).
 1.10  18-Jun-2011  matt struct device * -> device_t
struct cfdata * -> cfdata_t
use device accessors, use device_private.
some softc/device_t splits (macppc needs a bunch more)
aprint*_dev used considerably more

 1.1  27-Feb-2001  matt Add a gpio device to handle the gpio device & extint-gpio1
interrupt. (think ibook/powerbook)
 1.2.4.2  12-Mar-2001  bouyer Sync with HEAD.
 1.2.4.1  27-Feb-2001  bouyer file gpio.c was added on branch thorpej_scsipi on 2001-03-12 13:29:00 +0000

 1.3.8.3  03-Jan-2003  thorpej Sync with HEAD.
 1.3.8.2  18-Oct-2002  nathanw Catch up to -current.
 1.3.8.1  19-Jun-2001  nathanw file gpio.c was added on branch nathanw_sa on 2002-10-18 02:38:34 +0000
 1.3.2.1  10-Oct-2002  jdolecek sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work
 1.6.2.3  21-Sep-2004  skrll Fix the sync with head I botched.
 1.6.2.2  18-Sep-2004  skrll Sync with HEAD.
 1.6.2.1  03-Aug-2004  skrll Sync with HEAD
 1.8.82.1  18-Jun-2008  simonb Sync with head.
 1.8.80.1  23-Jun-2008  wrstuden Sync w/ -current. 34 merge conflicts to follow.
 1.8.78.1  04-May-2009  yamt sync with head.
 1.8.76.1  17-Jun-2008  yamt sync with head.
 1.8.74.1  29-Jun-2008  mjf Sync with HEAD.
 1.9.28.1  23-Jun-2011  cherry Catchup with rmind-uvmplock merge.
 1.11.12.1  20-Nov-2012  tls Resync to 2012-11-19 00:00:00 UTC
 1.11.2.1  30-Oct-2012  yamt sync with head

 1.13.2.2  04-Apr-2021  thorpej Associate the OpenFirmware phandle associated with a found device (including
PCI bus instances) by using CFARG_DEVHANDLE.
 1.13.2.1  21-Mar-2021  thorpej Give config_found() the same variadic arguments treatment as
config_search(). This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls. Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.
 1.14.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
