lisa* at iic?

The lisa driver provides support for the ST LIS331DL 3-axis digital output accelerometer. A total of 3 sensors are provided, one for each axis (X, Y and Z). Each reading from LIS331DL is represented by an 8-bit 2's complement number.

Sensor values are made available through the HW_SENSORS sysctl(2) interface, and can be monitored with the systat(1) sensors view, sensorsd(8) and sysctl(8) hw.sensors.
