+ * This driver tries to support the "digital" accelerometer chips from
+ * STMicroelectronics such as LIS3LV02DL, LIS302DL, LIS3L02DQ, LIS331DL,
+ * LIS331DLH, LIS35DE, or LIS202DL. They are very similar in terms of
+ * programming, with almost the same registers. In addition to differing
+ * on physical properties, they differ on the number of axes (2/3),
+ * precision (8/12 bits), and special features (freefall detection,
+ * click...). Unfortunately, not all the differences can be probed via
+ * a register. They can be connected either via I²C or SPI.
