| title: STMicroelectronics MEMS sensors |
| |
| 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. |
