Merge tag 'i3c/fixes-for-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux

2026-03-14T23:25:10+00:00

Pull i3c fixes from Alexandre Belloni:
 "This introduces the I3C_OR_I2C symbol which is not a fix per se but is
  affecting multiple subsystems so it is included to ease
  synchronization.

  Apart from that, Adrian is mostly fixing the mipi-i3c-hci driver DMA
  handling, and I took the opportunity to add two fixes for the dw-i3c
  driver.

  Subsystem:
   - simplify combined i3c/i2c dependencies

  Drivers:
   - dw: handle 2C properly, fix possible race condition
   - mipi-i3c-hci: many DMA related fixes"

iio: magnetometer: bmc150_magn: use automated cleanup for mutex

2026-03-02T21:15:28+00:00

Use guard() and scoped_guard() to replace manual mutex lock/unlock
calls. This simplifies error handling and ensures RAII-style cleanup.

guard() is used in read_raw, write_raw, trig_reen, and
trigger_set_state. Case blocks using guard() in read_raw and write_raw
are wrapped in braces at the case label level to ensure clear scope for
the cleanup guards.

A bmc150_magn_set_power_mode_locked() helper is added to deduplicate
the lock-call-unlock pattern used by remove, runtime_suspend, suspend,
and resume.

The trigger_handler function is left unchanged as mixing guard() with
goto error paths can be fragile.

i3c: simplify combined i3c/i2c dependencies

2026-02-27T15:33:07+00:00

All combined i2c/i3c drivers appear to suffer from the same link
time problem when CONFIG_I3C is set to 'm':

arm-linux-gnueabi-ld: drivers/iio/magnetometer/mmc5633.o: in function `mmc5633_i3c_driver_init':
mmc5633.c:(.init.text+0x30): undefined reference to `i3c_driver_register_with_owner'

This was previously fixed every time by marking individual
drivers as 'depends on I2C; depends on I3C || !I3C', but this gets
tedious and is somewhat confusing.

Add a Kconfig symbol 'I3C_OR_I2C' to help replace those dependencies,
and use this in all the existing drivers that had already fixed it
as well as the new mmc5633 driver.

iio: magnetometer: tlv493d: remove erroneous shift in X-axis data

2026-02-23T08:24:38+00:00

TLV493D_BX2_MAG_X_AXIS_LSB is defined as GENMASK(7, 4). FIELD_GET()
already right-shifts bits [7:4] to [3:0], so the additional >> 4
discards most of the X-axis low nibble. The Y and Z axes correctly
omit this extra shift. Remove it.

iio: magnetometer: si7210: simplify probe with devm_regulator_get_enable_read_voltage()

2026-02-23T08:24:23+00:00

Simplify probe by using devm_regulator_get_enable_read_voltage() to
get, enable and read the regulator voltage in a single call, caching
the value at probe time.

This is a functional change as VDD voltage is now read once at probe
rather than dynamically on each temperature measurement. However, in
real deployments it is very rare for VDD to change after initial probe.

iio: magnetometer: bmc150_magn: minor formatting cleanup

2026-02-23T08:24:23+00:00

Improve initializer list style for bmc150_magn_samp_freq_table by
moving the opening brace to its own line and using one entry per line
with proper indentation and spaces inside braces.

Add spaces inside braces for initializer lists in the preset table
for consistency.

Fix indentation of bmc150_magn_scan_masks array. No functional changes.

iio: magnetometer: bmc150_magn: replace msleep with fsleep

2026-02-23T08:24:23+00:00

Replace msleep(5) with fsleep(5 * USEC_PER_MSEC) to allow the kernel
to select the most appropriate delay mechanism based on duration.
Using USEC_PER_MSEC makes the unit conversion explicit.

iio: magn: mmc5633: Fix Kconfig for combination of I3C as module and driver builtin

2026-02-01T16:53:35+00:00

Fix based on similar fix in:
commit 83b645ee43f7 ("hwmon: tmp108: fix I3C dependency")

Note to keep things simple I'm now requiring I2C.
That can probably be relaxed in future, but I want to reduce the test
set of builds for now given this is blocker for the main IIO pull request.
