This driver provides support for the LIS3LV02Dx accelerometer. 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). 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
the laptop to act as a pinball machine-esque joystick. On HP laptops,
if the led infrastructure is activated, support for a led indicating
disk protection will be provided as hp:red:hddprotection.

This driver can also be built as modules. If so, the core module
will be called lis3lv02d and a specific module for HP laptops will be
called hp_accel.

Say Y here if you have an applicable laptop and want to experience
the awesome power of lis3lv02d.
