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.
