iio: accel: sca3300: Add support for SCL3300
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 Signed-off-by: LI Qingwu <Qing-wu.Li@leica-geosystems.com.cn> Reviewed-by: Tomas Melin <tomas.melin@vaisala.com> Link: https://lore.kernel.org/r/20220529061853.3044893-5-Qing-wu.Li@leica-geosystems.com.cn Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
