 1.9  08-Aug-2023  mrg fix array vs pointer function declaration.

also, in some callers, and make sure to provide all the accessed
backing for a string array.

found by GCC 12.
 1.8  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.7  24-Apr-2021  thorpej branches: 1.7.8;
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?).
 1.6  25-Apr-2014  riastradh branches: 1.6.2; 1.6.4; 1.6.8; 1.6.50;
Fix binary search logic.

Doesn't matter for the one user of this, but still.
 1.5  01-Apr-2014  riastradh branches: 1.5.2;
Fix copypasta error in apple_smc_write_key_4: uint32_t, not uint16_t.
 1.4  01-Apr-2014  riastradh Polish the Apple SMC code with commentary and little fixes.
 1.3  01-Apr-2014  riastradh Rework Apple SMC device attachment goo again.

Less bookkeeping at the expense of iteration over all devices when
rescanning applesmc.
 1.2  01-Apr-2014  riastradh Rework Apple SMC attachment goo and split into multiple modules.

The four modules are apple_smc for the core functions, apple_smc_acpi
for attachment at acpi, and apple_smc_fan & apple_smc_temp for stuff
on the SMC.

Seems like there's a lot more bookkeeping necessary to maintain
children of an applesmc device implemented by loadable modules.
Maybe there's a better way I just haven't figured out yet.
 1.1  01-Apr-2014  riastradh First draft of drivers for the Apple System Management Controller.

Device interface derived by reading the Linux driver source code and
<http:///www.parhelia.ch/blog/statics/k3_keys.html> as of 2012-12-05.

Includes support for attaching fan and temperature sensors to sysmon.
No accelerometer yet.

Compile-tested only, based on some run-testing of experiments from
userland. Module attachment is not quite finished, so it won't work
yet.
 1.5.2.1  10-Aug-2014  tls Rebase.
 1.6.50.5  05-Apr-2021  thorpej config_match() -> config_probe() for the straight-forward indirect config
cases. There are still a few odd balls using config_match() which should
be sorted out later.
 1.6.50.4  04-Apr-2021  thorpej CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
 1.6.50.3  03-Apr-2021  thorpej config_attach_loc() -> config_attach() with CFARG_LOCATORS argument.
 1.6.50.2  28-Mar-2021  thorpej This driver only has a single interface attribute, so no need to be expicit
about it. That interface attribute has no locators, so don't pass them
to config_search().
 1.6.50.1  20-Mar-2021  thorpej The proliferation if config_search_*() and config_found_*() combinations
is a little absurd, so begin to tidy this up:

- Introduce a new cfarg_t enumerated type, that defines the types of
tag-value variadic arguments that can be passed to the various
config_*() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS,
for now, plus a CFARG_EOL sentinel).
- Collapse config_search_*() into config_search() that takes these
variadic arguments.
- Convert all call sites of config_search_*() to the new signature.
Noticed several incorrect usages along the way, which will be
audited in a future commit.
 1.6.8.2  20-Aug-2014  tls Rebase to HEAD as of a few days ago.
 1.6.8.1  25-Apr-2014  tls file apple_smc.c was added on branch tls-maxphys on 2014-08-20 00:03:37 +0000
 1.6.4.2  22-May-2014  yamt sync with head.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs. ("Protocol error: too many arguments")
 1.6.4.1  25-Apr-2014  yamt file apple_smc.c was added on branch yamt-pagecache on 2014-05-22 11:40:21 +0000
 1.6.2.2  18-May-2014  rmind sync with head
 1.6.2.1  25-Apr-2014  rmind file apple_smc.c was added on branch rmind-smpnet on 2014-05-18 17:45:37 +0000
 1.7.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
