[PATCH v2 0/9] add i2c controller support to st_lsm6dsx driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Introduce i2c controller support to st_lsm6dsx driver for lsm6dso sensor.
st_lsm6dsx sensor-hub supports up to 3 concurrent slave devices.
Add register map for lis2mdl magnetometer sensor.
Add hw FIFO support to st_lsm6dsx sensorhub driver.

Changes since v1:
- move back st_lsm6dsx_set_fifo_mode routine in fifo_lock critical section
  in st_lsm6dsx_flush_fifo
- improve documentation
- move st_lsm6dsx_sensor_set_enable definition in a separated patch
- move st_lsm6dsx_push_tagged_data definition in a separated patch
- use proper ts_ref for ext devices in st_lsm6dsx_push_tagged_data
- fix invalid iio_dev identification in st_lsm6dsx_push_tagged_data
  when ST_LSM6DSX_EXT1_TAG is read from the FIFO
- refactor st_lsm6dsx_shub_probe moving wai check in a dedicated routine
- fix abi issue in scale_available definition
