Say yes here to build support for STMicroelectronics LSM6DSx imu
sensor. Supported devices: lsm6ds3, lsm6ds3h, lsm6dsl, lsm6dsm,
ism330dlc, lsm6dso, lsm6dsox, asm330lhh, lsm6dsr
ism330dlc, lsm6dso, lsm6dsox, asm330lhh, lsm6dsr, lsm6ds3tr-c
To compile this driver as a module, choose M here: the module
will be called st_lsm6dsx.
