This is a driver for laptops built by Compal, and some models by
other brands (e.g. Dell, Toshiba).
- It adds support for rfkill, Bluetooth, WLAN and LCD brightness
- control.
+ It adds support for rfkill, Bluetooth, WLAN, LCD brightness, hwmon
+ and battery charging level control.
For a (possibly incomplete) list of supported laptops, please refer
to: Documentation/platform/x86-laptop-drivers.txt
If you have a recent Toshiba laptop with a built-in accelerometer
device, say Y.
