37  * Due to the time required for the sensor to startup, this driver is meant to
38  * be used in an asynchronous fashion. The caller must first activate the
39  * sensor by calling SENSORS_ACTIVATE(). This will trigger the sensor's startup
40  * sequence, but the call will not wait for it to complete so that the CPU can
41  * perform other tasks or drop to a low power mode.
42  *
43  * Once the sensor is stable, the driver will generate a sensors_changed event.
44  *
45  * We take readings in "Forced" mode. In this mode, the BMP will take a single
46  * measurement and it will then automatically go to sleep.
47  *
48  * SENSORS_ACTIVATE must be called again to trigger a new reading cycle
