iio: magnetometer: add support for QST QMC6308

2026-07-26T18:19:36+00:00

The QST QMC6308 is a 3-axis anisotropic magnetoresistive (AMR) magnetometer on I2C, found e.g. in the Fairphone 6. Its register map is not compatible with the QMC5883L's, so add a separate driver rather than extending the QMC5883L driver. Support raw X/Y/Z reads, output data rate, field range, filter oversampling ratio, the mount matrix, and runtime PM. Run measurements in the chip's periodic "normal" mode paced by the DRDY flag rather than in its one-shot "single" mode: the datasheet specifies no conversion time that could bound a one-shot wait, while normal mode is paced by the specified output data rates, which also keeps the sampling_frequency ABI meaningful. Runtime PM puts the chip into its suspend mode after 500 ms without a reading, dropping supply current to a few microamps. The suspended chip retains its registers and keeps responding on I2C, so resuming only rewrites the mode field and discards one stale sample, and configuration changes apply even while suspended; VDD is left enabled across runtime suspend.

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: 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: add support for Infineon TLV493D 3D Magentic sensor

2025-09-10T18:47:05+00:00

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].
