Subject: [PATCH V6 4/5] iio: accel: sca3300: Add support for SCL3300
Date: Fri, 13 May 2022 12:41:34 +0000	[thread overview]
Message-ID: <20220513124135.1295822-5-Qing-wu.Li@leica-geosystems.com.cn> (raw)
In-Reply-To: <20220513124135.1295822-1-Qing-wu.Li@leica-geosystems.com.cn>

Add support for Murata SCL3300, a 3-axis MEMS accelerometer.
Same as SCA3300, it has the accelerometer and temperature output.

Datasheet: www.murata.com/en-us/products/sensor/inclinometer/overview/lineup/scl3300
