Since st_lsm6dsx i2c master controller relies on accel device as trigger and slave devices can run at different ODRs we must select an accel_odr >= slave_odr. Report real accel ODR in st_lsm6dsx_check_odr() in order to properly set sensor frequency in st_lsm6dsx_write_raw and avoid to report unsupported frequency Fixes: 6ffb55e5009ff ("iio: imu: st_lsm6dsx: introduce ST_LSM6DSX_ID_EXT sensor ids") Signed-off-by: Lorenzo Bianconi <lorenzo@xxxxxxxxxx> --- drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c b/drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c index 1f28a7733fc0..c53c03ec2423 100644 --- a/drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c +++ b/drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c @@ -1362,8 +1362,7 @@ int st_lsm6dsx_check_odr(struct st_lsm6dsx_sensor *sensor, u16 odr, u8 *val) return -EINVAL; *val = odr_table->odr_avl[i].val; - - return 0; + return odr_table->odr_avl[i].hz; } static u16 st_lsm6dsx_check_odr_dependency(struct st_lsm6dsx_hw *hw, u16 odr, @@ -1527,8 +1526,10 @@ static int st_lsm6dsx_write_raw(struct iio_dev *iio_dev, case IIO_CHAN_INFO_SAMP_FREQ: { u8 data; - err = st_lsm6dsx_check_odr(sensor, val, &data); - if (!err) + val = st_lsm6dsx_check_odr(sensor, val, &data); + if (val < 0) + err = val; + else sensor->odr = val; break; } -- 2.21.0
