riastradh | i2c(9): Nix smbus intr API.
It was introduced in 2007 for some Xbox thing which was removed in
2011. The API and the threads it spawned have been sitting around
idly for over a decade serving no purpose -- sometimes causing kernel
lock spinouts in the event of panic.
Add ic_tag_private to obviate need for future ABI changes. Not
currently used, but we can privately allocate memory in iic_tag_init
for the purpose later if need be without changing ABI.
XXX kernel revbump -- changes struct i2c_controller

thorpej | branches: 1.16.8;
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?).

thorpej | branches: 1.15.2;
Use acpi_compatible_match().

thorpej | branches: 1.14.8;
Cleanup i2c bus acquire / release, centralizing all of the logic into
iic_acquire_bus() / iic_release_bus(). "acquire" and "release" hooks
no longer need to be provided by back-end controller drivers (only if
they need special handling, e.g. powering on the i2c controller).
This results in the removal of a bunch of rendundant code from each
back-end controller driver.
Assert that we are not in hard interrupt context in iic_acquire_bus(),
iic_exec(), and iic_release_bus().

jruoho | branches: 1.13.60;
Refactor to make this more readable. No functional change.
|
| 1.12 |
| 28-Jul-2010 |
jruoho | Remove also the HIDs from previous.
|
| 1.11 |
| 28-Jul-2010 |
jruoho | Remove the homegrown attempt to match the parent PCI bus. This was only used
for descriptive purposes, and for such purposes the ACPIVERBOSE output is
much better.
|
| 1.10 |
| 15-Apr-2010 |
jruoho | As discussed with jmcneill@, install a global "bus notification handler"
that receives all notifications and deliver notifications to drivers via it.
|
| 1.9 |
| 05-Mar-2010 |
jruoho | branches: 1.9.2; 1.9.4;
Remove <dev/acpi/acpica.h> from all files. It is included from
<dev/acpi/acpivar.h>. Ditto for <dev/sysmon/sysmonvar.h>, <sys/bus.h>,
<dev/pci/pcivar.h>, and <dev/isa/isavar.h>.
Also nuke a lot of unused and invalid headers. Some of these are audibly
provided by standard headers (namely <sys/param.h> and <sys/device.h>), some
have nothing to do with ACPI devices (e.g. <sys/syslog.h>), and some are
nonexistent local includes (e.g. "mpu_ym.h"). Moreoever, try to group the
includes into their respective blocks.
Tested with GENERIC and ALL (i386). No functional change.

jruoho | Fix two memory leaks.

jruoho | Fix ACPI_DEBUG build failures reported by Greg A. Woods.

| 04-Mar-2010 |
pgoyette | This really should be ACPI_BUS_COMPONENT
Maybe I should stay out the acpi stuff? :)
|
| 1.5 |
| 04-Mar-2010 |
pgoyette | Fix this correctly. Thanks jruoho@
|
| 1.4 |
| 04-Mar-2010 |
pgoyette | Replace ACPI_FREE() with AcpiOsFree() so we no longer need to define
_COMPONENT (we don't have a bit defined for SMBUS anyway). This was
uncovered by turning on ACPI_DEBUG for the i386 ALL kernel config.

| 1.3 |
| 01-Mar-2010 |
jruoho | Destroy the callout(9) when detaching. Also evaluate the removal of the
notify handler before going to demolishing business.
|
| 1.2 |
| 01-Mar-2010 |
jruoho | Semantics:
* Use ACPI_ADR_PCI_DEV(x) and ACPI_ADR_PCI_FUNC(x).
* !ACPI_FAILURE -> ACPI_SUCCESS, UINT32 -> uint32_t
* Remove whitespace.
