| 23-Sep-2025 |
thorpej | Move iic_{acquire,release}_bus_lock() into i2c_exec.c from i2c_subr.c
to deal with MODULARization / attribute entanglements.
Fixes e.g. alpha INSTALL kernel build issue after recent i2c work.
|
| 1.20 |
| 21-Sep-2025 |
thorpej | Tidy up the i2c subsystem ABI:
- Remove unused structures and deprecated fields (ia_prop, ia_cookie,
ia_cookietype).
- Normalize the "compatible" list; we get it as a strlist, don't bother
converting to an array when we can use the strlist as-is. (This is
invisible to drivers using the API correctly, but it does change
the i2c_attach_args).
- Add a "channel" field to i2c_tag_t, for use by controllers with
built-in i2c muxes or discrete i2c muxes.
Bienvenido, NetBSD 11.99.3.
|
| 1.19 |
| 20-Sep-2025 |
thorpej | Put the "acquire i2c bus lock" logic (sleep vs try) into a helper function
so it can shared.
|
| 1.18 |
| 24-Oct-2022 |
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

| 1.17 |
| 12-Oct-2021 |
andvar | fix various typos, mainly in comments.
|
| 1.16 |
| 19-Apr-2020 |
thorpej | In iic_acquire_bus(), unlock the bus lock if the back-end returns an
error from its acquire-bus function.
|
| 1.15 |
| 02-Jan-2020 |
thorpej | branches: 1.15.6;
Also force I2C_F_POLL if shutting_down.
|
| 1.14 |
| 23-Dec-2019 |
thorpej | Disable the not-in-interrupt assertions for now; more work needs to be
done in several i2c client drivers.
|
| 1.13 |
| 22-Dec-2019 |
thorpej | 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().
|
| 1.12 |
| 25-Jul-2019 |
thorpej | If cold, automagically set I2C_F_POLL.
|
| 1.11 |
| 10-Dec-2018 |
thorpej | Make i2c_acquire_bus() / i2c_release_bus() real symbols.
|
| 1.10 |

jmcneill | branches: 1.10.16; 1.10.18;
i2c devices don't actually have a dependency on "iic" (the bus driver)
but on "i2cexec". Create an i2cexec module (i2c_exec.c) to mirror the
dependencies in files.i2c and switch device drivers to depend on "i2cexec"
module instead.
A kernel with a USB stack and no I2C controller / bus attachment would spit
out a bunch of "WARNING: module error: can't find builtin dependency `iic'"
messages at boot. This change solves that problem.

| 1.9 |
| 12-Sep-2013 |
martin | branches: 1.9.4; 1.9.6;
Fix evil "sizeof(void*)" botch
|
| 1.8 |
| 22-Apr-2012 |
pgoyette | branches: 1.8.2; 1.8.4;
Identify SMBus block-mode operations.
XXX Nothing in the kernel issues block-mode commands, and each i2c bus
XXX driver needs its own support for the block-mode operations.
|
| 1.7 |
| 03-Feb-2009 |
pgoyette | branches: 1.7.14; 1.7.18;
Handle i2c quick_read/quick_write bus protocol in the generic i2c_exec()
routine, since we have already have the iic_smbus_* interfaces.
NOTE: i2c controllers that provide their own i2c_exec() routine also need
to be modified. I'll be committing most of these shortly.

christos | Don't return random errors.
|

thorpej | New generic I2C framework. Supports bit-bang and "intelligent" I2C
interface controllers (of varying intelligence levels).
