i3c: simplify combined i3c/i2c dependencies

2026-02-27T15:33:07Z

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

2026-02-01T16:53:35Z

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: add support for Infineon TLV493D 3D Magentic sensor

2025-09-10T18:47:05Z

The Infineon TLV493D is a Low-Power 3D Magnetic Sensor. The Sensor applications includes joysticks, control elements (white goods, multifunction knops), or electric meters (anti tampering) and any other application that requires accurate angular measurements at low power consumptions. The Sensor is configured over I2C, and as part of Sensor measurement data it provides 3-Axis magnetic fields and temperature core measurement. The driver supports raw value read and buffered input via external trigger to allow streaming values with the same sensing timestamp. While the sensor has an interrupt pin multiplexed with an I2C SCL pin. But for bus configurations interrupt(INT) is not recommended, unless timing constraints between I2C data transfers and interrupt pulses are monitored and aligned. The Sensor's I2C register map and mode information is described in product User Manual [1].

iio: magnetometer: add Allegro MicroSystems ALS31300 3-D Linear Hall Effect driver

2024-11-03T20:33:44Z

The Allegro MicroSystems ALS31300 is a 3-D Linear Hall Effect Sensor mainly used for 3D head-on motion sensing applications. The device is configured over I2C, and as part of the Sensor data the temperature core is also provided. While the device provides an IRQ gpio, it depends on a configuration programmed into the internal EEPROM, thus only the default mode is supported and buffered input via trigger is also supported to allow streaming values with the same sensing timestamp. The device can be configured with different sensitivities in factory, but the sensitivity value used to calculate value into the Gauss unit is not available from registers, thus the sensitivity is provided by the compatible/device-id string which is based on the part number as described in the datasheet page 2.
