842 help
843 This driver provides support for the LIS3LV02Dx accelerometer. In
844 particular, it can be found in a number of HP laptops, which have the
845 "Mobile Data Protection System 3D" or "3D DriveGuard" feature. On such
846 systems the driver should load automatically (via ACPI). The
847 accelerometer might also be found in other systems, connected via SPI
848 or I2C. The accelerometer data is readable via
849 /sys/devices/platform/lis3lv02d.
850
851 This driver also provides an absolute input class device, allowing
852 the laptop to act as a pinball machine-esque joystick.

855 will be called lis3lv02d.
