iio: imu: bno055: Fix missing Kconfig dependencies

2023-10-05T17:06:45+00:00

This driver uses IIO triggered buffers so it needs to select them in
Kconfig.

iio: imu: lsm6dsx: Fix mount matrix retrieval

2023-07-23T12:40:45+00:00

The function lsm6dsx_get_acpi_mount_matrix should return an error when ACPI
support is not enabled to allow executing iio_read_mount_matrix in the
probe function.

iio: imu: adis16475.c: Add has_burst32 flag to adis16477 devices

2023-07-23T12:24:33+00:00

adis16477 devices support burst32 function, thus has_burst32
flag should be set to true.

iio: imu: inv_mpu6050: read the full fifo when processing data

2023-07-20T18:21:30+00:00

When processing data read the full fifo data in 1 time. If there
are several samples in the FIFO, it means we are experiencing
system delay. In this case, it is better to read all data with 1
bus access than to add additional latency by doing several ones.

This requires to use a bigger buffer depending on chip FIFO size
and do an additional local data copy before sending. But the cost
is minimal and behavior is still better like this under system
heavy load.

iio: imu: inv_mpu6050: use the common inv_sensors timestamp module

2023-07-20T18:21:29+00:00

Replace timestamping by the new common inv_sensors timestamp
module. The principle behind is the same but the implementation in
the new module is far better providing less jitter and a better
estimation.

iio: make invensense timestamp module generic

2023-07-20T18:21:28+00:00

Rename common module to inv_sensors_timestamp, add configuration
at init (chip internal clock, acceptable jitter, ...) and update
inv_icm42600 driver integration.

iio: move inv_icm42600 timestamp module in common

2023-07-20T18:21:28+00:00

Create new inv_sensors common modules and move inv_icm42600
timestamp module inside. This module will be used by IMUs and
also in the future by other chips.

Modify inv_icm42600 driver to use timestamp module and do some
headers cleanup.
