- Say Y here if you want the I2C chip drivers to produce a bunch of
- debug messages to the system log. Select this if you are having
- a problem with I2C support and want to see more of what is going
- on.
+ 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
+ information on the feature, refer to Documentation/hwmon/lis3lv02d.
+
+ 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.
