Subject: [PATCH V5 4/5] iio: accel: sca3300: Add support for SCL3300
Date: Thu, 12 May 2022 16:03:11 +0000 [thread overview]
Message-ID: <20220512160312.3880433-5-Qing-wu.Li@leica-geosystems.com.cn> (raw)
In-Reply-To: <20220512160312.3880433-1-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:
