iio: add MEMSensing MSA311 3-axis accelerometer driver

2022-08-30T17:35:38Z

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

2022-02-21T19:33:06Z

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

2022-01-23T18:03:35Z

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.

iio: accel: adxl355: Add triggered buffer support

2021-09-14T11:00:35Z

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.

iio: accel: bmc150: Add support for BMC156

2021-08-08T15:48:30Z

BMC156 is another accelerometer that works just fine with the bmc150-accel driver. It's very similar to BMC150 (also a accelerometer + magnetometer combo) but with only one accelerometer interrupt pin. It would make sense if only INT1 was exposed but someone at Bosch decided to only have an INT2 pin. Try to deal with this by making use of the INT2 support introduced in the previous commit and force using INT2 for BMC156. To detect that we need to bring up a simplified version of the previous type IDs. Note that unlike the type IDs removed in commit c06a6aba6835 ("iio: accel: bmc150: Drop misleading/duplicate chip identifiers") here I only add one for the special case of BMC156. Everything else still happens by reading the CHIP_ID register since the chip type information often is not accurate in ACPI tables.
