| description: | |
| Note that whilst this covers many STMicro MEMs sensors, some more complex |
| IMUs need their own bindings. |
| 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. |
