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

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"

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: 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.

iio: magnetometer: Remove IRQF_ONESHOT

2026-01-29T16:13:11+00:00

Passing IRQF_ONESHOT ensures that the interrupt source is masked until
the secondary (threaded) handler is done. If only a primary handler is
used then the flag makes no sense because the interrupt can not fire
(again) while its handler is running.
The flag also disallows force-threading of the primary handler and the
irq-core will warn about this.
The force-threading functionality is required on PREEMPT_RT because the
handler is using locks with can sleep on PREEMPT_RT.

Remove IRQF_ONESHOT from irqflags.

iio: Replace IRQF_ONESHOT with IRQF_NO_THREAD

2026-01-29T16:11:50+00:00

Passing IRQF_ONESHOT ensures that the interrupt source is masked until
the secondary (threaded) handler is done. If only a primary handler is
used then the flag makes no sense because the interrupt can not fire
(again) while its handler is running.
The flag also disallows force-threading of the primary handler and the

The intention here was probably not allowing forced-threading for
handlers such as iio_trigger_generic_data_rdy_poll() will intends to
invoke hard-interrupt handlers.

Replace IRQF_ONESHOT with IRQF_NO_THREAD.

iio: magnetometer: tmag5273: remove unused IIO_CHAN_INFO_PROCESSED handling

2025-09-10T18:47:06+00:00

The tmag5273 driver does not advertise IIO_CHAN_INFO_PROCESSED in its
info_mask_* fields, so the corresponding case in read_raw()/write_raw()
is never used.
Drop the dead code to reduce unnecessary branches and improve clarity.
