Subject: [PATCH v3 3/5] iio: imu: st_lsm6sdx: move register definitions to sensor_settings struct
Date: Thu, 25 Jul 2019 07:31:30 +0200 [thread overview]
Message-ID: <20190725053132.9589-4-martin.kepplinger@puri.sm> (raw)
In-Reply-To: <20190725053132.9589-1-martin.kepplinger@puri.sm>
Move some register definitions to the per-device array of struct
st_lsm6dsx_sensor_settings in order to simplify adding new sensor
devices to the driver.
Also, remove completely unused register definitions.
Signed-off-by: Martin Kepplinger <martin.kepplinger@puri.sm>
