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.

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].

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

2024-11-03T20:33:44+00:00

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.

iio: magnetometer: Add driver for Yamaha YAS530

2021-01-09T21:52:46+00:00

This adds an IIO magnetometer driver for the Yamaha YAS530 family of magnetometer/compass chips YAS530, YAS532 and YAS533. A quick survey of the source code released by different vendors reveal that we have these variants in the family with some deployments listed: * YAS529 MS-3C (2005 Samsung Aries) * YAS530 MS-3E (2011 Samsung Galaxy S Advance) * YAS532 MS-3R (2011 Samsung Galaxy S4) * YAS533 MS-3F (Vivo 1633, 1707, V3, Y21L) * (YAS534 is a magnetic switch) * YAS535 MS-6C * YAS536 MS-3W * YAS537 MS-3T (2015 Samsung Galaxy S6, Note 5) * YAS539 MS-3S (2018 Samsung Galaxy A7 SM-A750FN) The YAS529 is so significantly different from the YAS53x variants that it will require its own driver. The YAS537 and YAS539 have slightly different register sets but have strong similarities so a common driver patching this one will probably be reasonable. The source code for Samsung Galaxy A7's YAS539 is not that is significantly different from the YAS530 in the Galaxy S Advance, so I believe we will only need this one driver with quirks to handle all of them. The YAS539 is actively announced on Yamaha's devices site: https://device.yamaha.com/en/lsi/products/e_compass/ This is a driver written from scratch using buffered IIO and runtime PM handling regulators and reset. Thanks to Andy Shevchenko for great help in finding all the special kernel infrastructure functions and quirks during review of this driver.
