iio: kx022a: Support ROHM KX132ACR-LBZ

2023-10-05T13:44:06+00:00

dt-bindings: iio: Add KX132ACR-LBZ accelerometer ROHM KX132ACR-LBZ is an accelerometer for industrial applications. It has a subset of KX022A functionalities, dropping support for tap, free fall and tilt detection engines. Also, the register interface is an exact subset of what is found on KX022A (except the WHO_AM_I register value). Add support for KX132ACR-LBZ.

iio: accel: Add support for Kionix/ROHM KX132-1211 accelerometer

2023-09-17T09:44:57+00:00

Kionix KX132-1211 is a tri-axis 16-bit accelerometer that can support ranges from ±2G to ±16G, digital output through I²C/SPI. Add support for basic accelerometer features such as reading acceleration via IIO using raw reads, triggered buffer (data-ready), or the WMI IRQ.

iio: accel: st_accel: Add LSM303C

2023-01-08T13:01:02+00:00

The accelerometer part of ST LSM303C is similar (perhaps even identical) to the already supported standalone LIS2HH12 accelerometer, so just add the new st,lsm303c-accel compatible for the existing definitions.

iio: accel: Support Kionix/ROHM KX022A accelerometer

2022-11-23T19:44:03+00:00

KX022A is a 3-axis accelerometer from ROHM/Kionix. The sensor features include variable ODRs, I2C and SPI control, FIFO/LIFO with watermark IRQ, tap/motion detection, wake-up & back-to-sleep events, four acceleration ranges (2, 4, 8 and 16g), and probably some other cool features. Add support for the basic accelerometer features such as getting the acceleration data via IIO. (raw reads, triggered buffer [data-ready] or using the WMI IRQ). Important things to be added include the double-tap, motion detection and wake-up as well as the runtime power management.

iio: add MEMSensing MSA311 3-axis accelerometer driver

2022-08-30T17:35:38+00:00

MSA311 is a tri-axial, low-g accelerometer with I2C digital output for sensitivity consumer applications. It has dynamic user-selectable full scales range of +-2g/+-4g/+-8g/+-16g and allows acceleration measurements with output data rates from 1Hz to 1000Hz. This driver supports following MSA311 features: - IIO interface - Different power modes: NORMAL and SUSPEND (using pm_runtime) - ODR (Output Data Rate) selection - Scale and samp_freq selection - IIO triggered buffer, IIO reg access - NEW_DATA interrupt + trigger Below features to be done: - Motion Events: ACTIVE, TAP, ORIENT, FREEFALL - Low Power mode Datasheet: https://cdn-shop.adafruit.com/product-files/5309/MSA311-V1.1-ENG.pdf Signed-off-by: Dmitry Rokosov Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20220822175011.2886-4-ddrokosov@sberdevices.ru Signed-off-by: Jonathan Cameron

iio: accel: add ADXL367 driver

2022-02-21T19:33:06+00:00

The ADXL367 is an ultralow power, 3-axis MEMS accelerometer. The ADXL367 does not alias input signals to achieve ultralow power consumption, it samples the full bandwidth of the sensor at all data rates. Measurement ranges of +-2g, +-4g, and +-8g are available, with a resolution of 0.25mg/LSB on the +-2 g range. In addition to its ultralow power consumption, the ADXL367 has many features to enable true system level power reduction. It includes a deep multimode output FIFO, a built-in micropower temperature sensor, and an internal ADC for synchronous conversion of an additional analog input.

iio: st_sensors: don't always auto-enable I2C and SPI interface drivers

2022-01-23T18:03:35+00:00

This patch makes I2C and SPI interface drivers for STMicroelectronics sensor chips individually selectable via Kconfig. The default is kept unchanged - I2C and SPI interface drivers are still selected by default if the corresponding bus support is available. However, the patch makes it possible to explicitly disable drivers that are not needed for a particular target.

Provide a way for continuous data capture by setting up buffer support. The data ready signal exposed at the DRDY pin of the ADXL355 is exploited as a hardware interrupt which triggers to fill the buffer.
