Subject: [PATCH 5.3 162/180] iio: imu: st_lsm6dsx: move odr_table in st_lsm6dsx_sensor_settings
From: Lorenzo Bianconi <lorenzo@...nel.org>
[ Upstream commit 40dd7343897760c4b617faa78d213e25652de9a6 ]
Move sensor odr table in st_lsm6dsx_sensor_settings in order to support
sensors with different odr maps. This is a preliminary patch to add
support for LSM9DS1 sensor to st_lsm6dsx driver
