2025-09-10iio: magnetometer: add support for Infineon TLV493D 3D Magentic sensorDixit Parmar
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].

2024-11-03iio: magnetometer: add Allegro MicroSystems ALS31300 3-D Linear Hall Effect ↵Neil Armstrong
driver 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.

2022-08-15iio: magnetometer: yas530: Add YAS537 variantJakob Hauser
Add support for the magnetometer Yamaha YAS537. The additions are based on comparison of Yamaha Android kernel drivers for YAS532 [1] and YAS537 [2]. In the Yamaha YAS537 Android driver, there is an overflow/underflow control implemented. For regular usage, this seems not necessary. A similar overflow/ underflow control of Yamaha YAS530/532 Android driver isn't integrated in the mainline driver. It is therefore skipped for YAS537 in the mainline too. Also in the Yamaha YAS537 Android driver, at the end of the reset_yas537() function, a measurement is saved in "last_after_rcoil". Later on, this is compared to current measurements. If the difference gets too big, a new reset is initialized. The difference in measurements needs to be quite big, it's hard to say if this is necessary for regular operation. Therefore this isn't integrated in the mainline driver either.

2021-05-10iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGERAlexandru Ardelean
During commit 067fda1c065ff ("iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_trigger"), the iio_triggered_buffer_{setup,cleanup}() functions got moved under the hid-sensor-trigger module. The above change works fine, if any of the sensors get built. However, when only the common hid-sensor-trigger module gets built (and none of the drivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced. Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFER symbol. With this change the HID_SENSOR_IIO_TRIGGER (for the hid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER gets selected. All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, this change removes the IIO_TRIGGERED_BUFFER enforcement from each driver.

2021-01-09iio: magnetometer: Add driver for Yamaha YAS530Linus Walleij
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.

This adds a driver for the Asahi Kasei AK8974 and its sibling AMI305 magnetometers. It was deployed on scale in 2009 on a multitude of devices. It is distincly different from AK8973 and AK8975 and needs its own driver.

2013-08-03iio: Add a comment to about alphabetical order to Kconfigs and MakefilesLars-Peter Clausen
Keeping Makefile and Kconfig entries in alphabetical order usually works better than just appending new entries at the end, since it reduces the amount of conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to document that the entries should be kept in alphabetical order. Also reorder those entries which weren't in alphabetical order yet.

2013-05-22iio: STMicroelectronics: remove three useless selectsPaul Bolle
Drivers for STMicroelectronics accelerometers, gyroscopes, and magnetometers were added in v3.9. They all have a (similar) select statement in their Kconfig files for a non-existant Kconfig symbol. These select statements can safely be removed. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Acked-by: Denis Ciocca <denis.ciocca@st.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

Issues raised in last series to propose this have now been resolved so there should be no reason this driver cannot graduate from staging. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Laxman Dewangan <ldewangan@nvidia.com>
2013-01-31iio:magnetometer: Add STMicroelectronics magnetometers driverDenis Ciocca
This patch adds a generic magnetometer driver for STMicroelectronics magnetometers, currently it supports: LSM303DLHC, LSM303DLM, LIS3MDL. Signed-off-by: Denis Ciocca <denis.ciocca@st.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-12-27iio: hid-sensors: respect CONFIG_IIO_TRIGGERAlexander Holler
Not much to say, without that change, hid-sensor-trigger will be always compiled if HID_SENSOR_IIO_COMMON is selected which fails if CONFIG_IIO_TRIGGER is not set because CONFIG_IIO_CONSUMERS_PER_TRIGGER will not be defined.

2012-09-06iio: hid-sensors: Added Compass/Magnetometer 3Dsrinivas pandruvada
Added usage id processing for Compass 3D. This uses IIO interfaces for triggered buffer to present data to user mode.This uses HID sensor framework for registering callback events from the sensor hub.
