This driver provides support for the LIS3* accelerometers, such as the
LIS3LV02DL or the LIS331DL. In particular, it can be found in a number
of HP laptops, which have the "Mobile Data Protection System 3D" or
"3D DriveGuard" feature. On such systems the driver should load
automatically (via ACPI alias). The accelerometer might also be found
in other systems, connected via SPI or I2C. The accelerometer data is
readable via /sys/devices/platform/lis3lv02d.

This driver also provides an absolute input class device, allowing
a laptop to act as a pinball machine-esque joystick. It provides also
a misc device which can be used to detect free-fall. On HP laptops,
if the led infrastructure is activated, support for a led indicating
disk protection will be provided as hp::hddprotect. For more
