LIS2DS12 is an accelerometer by STMicroelectronics. It is identifiable by its WhoAmI value 0x43. Its register interface is not compatible with existing parts. For example: - The full-scale values are present in register 0x20, in bits 2 and 3 (mask 0x0c). Most other supported sensors have the register address set to 0x21, 0x23, 0x24, or 0x25. There is one sensor setting though (bearing WhoAmI 0x3b) which has it's address set to 0x20, but the mask is set to 0x20, not 0x0c. - The full-scale values 2G, 4G, 8G, and 16G correspond to the register values 0x00, 0x02, 0x03, 0x01 respectively. None of the sensor settings have the value 0x01 associated with 16G. Add the compatible string without any fallback.

description: The STMicroelectronics sensor devices are pretty straight-forward

I2C or SPI devices, all sharing the same device tree descriptions no matter

what type of sensor it is.
|
|
Note that whilst this covers many STMicro MEMs sensors, some more complex
|
|
IMUs need their own bindings.
