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 Lorenzo Bianconi (9): iio: imu: st_lsm6dsx: introduce locked read/write utility routines iio: imu: st_lsm6dsx: reload trimming parameter at bootstrap iio: imu: st_lsm6dsx: remove static from st_lsm6dsx_set_watermark iio: imu: st_lsm6dsx: introduce ST_LSM6DSX_ID_EXT sensor ids iio: imu: st_lsm6dsx: introduce st_lsm6dsx_sensor_set_enable routine iio: imu: st_lsm6dsx: add i2c embedded controller support iio: imu: st_lsm6dsx: add st_lsm6dsx_push_tagged_data routine iio: imu: st_lsm6dsx: add hw FIFO support to i2c controller dt-bindings: iio: imu: st_lsm6dsx: add support to i2c pullup resistors .../bindings/iio/imu/st_lsm6dsx.txt | 1 + drivers/iio/imu/st_lsm6dsx/Makefile | 3 +- drivers/iio/imu/st_lsm6dsx/st_lsm6dsx.h | 167 +++- .../iio/imu/st_lsm6dsx/st_lsm6dsx_buffer.c | 165 ++-- drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c | 283 +++++-- drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_shub.c | 777 ++++++++++++++++++ .../linux/platform_data/st_sensors_pdata.h | 2 + 7 files changed, 1263 insertions(+), 135 deletions(-) create mode 100644 drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_shub.c -- 2.19.1
