thorpej | Encapsulate what's needed to attach an I2C bus into a iicbus_attach()
inline.

thorpej | Merge thorpej-cfargs2.

| 24-Apr-2021 |
thorpej | branches: 1.24.8;
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?).

| 22-Dec-2019 |
thorpej | branches: 1.23.10;
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().

chs | branches: 1.22.18;
zero the i2c_attach_args structure before filling it in.
fixes occasional crashes in iic_attach().
|
| 1.21 |
| 13-Apr-2015 |
riastradh | Convert sys/dev to use <sys/rndsource.h>.
|
| 1.20 |
| 13-Jun-2013 |
tls | branches: 1.20.10;
Convert the entropy pool framework from pseudo-callout-driven to
soft interrupt driven operation.
Add a polling mode of operation -- now we can ask hardware random number
generators to top us up just when we need it (bcm2835_rng and amdpm
converted as examples).
Fix a stall noticed with repeated reads from /dev/random while testing.
|
| 1.19 |
| 27-Oct-2012 |
chs | split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
|
| 1.18 |
| 14-Feb-2012 |
pgoyette | branches: 1.18.6;
Replace the xxx_acquire()/xxx_release() rwlocks with mutexes. There are
only RW_WRITERs for these, and no RW_READERs, so no need to incur the
extra overhead of allowing for both. As discussed on tech-kern.
For piixpm and ichsmb, the acquire/release protocol needs to be used,
even if the request is I2C_F_POLL'd (or if the device supports only
polled mode). Otherwise multiple requests can be running at the same
time, and they stomp on each other and create anomolous results.

Fix build failure for !XBOX, pointed out by Paul Goyette on current-users
|
| 1.11 |
| 06-Feb-2007 |
jmcneill | Another Xbox hack;
If we're handling system management interrupts ourselves, the system locks
solid when the ACPI timer SCI fires. Disable this interrupt so we can have
an uptime of more than ~10 minutes.
|
| 1.10 |
| 05-Feb-2007 |
jmcneill | Disgusting Xbox hack;
The "pci0 dev 1 function 2" aka "System Management" on the nForce chipset
isn't detected on the Xbox. If XBOX is defined and arch_i386_is_xbox is
true, force intrline to 12 and map the system management IO space at
0x8000. We can now call iic_smbus_intr when a system management interrupt
takes place.
While we're here, make amdpm_smbus honour the I2C_F_POLL flag.
The Xbox no longer resets when you press the eject button.

| 06-Jan-2007 |
jmcneill | There is absolutely no way that this code could have worked for reading
values from the smbus before. amdpm_smbus_exec was using the values read
from the registers and using them as return values instead of filling in
the caller's buffer.
|

jmcneill | nForce uses a slightly different register offset for the smbus controls;
compensate for this.

of detection of the i2c address of the thermal monitor; it appears to be
at 0x2D on the S2881 and 0x2E on the S2882-D (kernel config examples
forthcoming).
