31  * fujitsu-laptop.c - Fujitsu laptop support, providing access to additional
32  * features made available on a range of Fujitsu laptops including the
33  * P2xxx/P5xxx/S6xxx/S7xxx series.
34  *
35  * This driver exports a few files in /sys/devices/platform/fujitsu-laptop/;
36  * others may be added at a later date.
37  *
38  *   lcd_level - Screen brightness: contains a single integer in the
39  *   range 0..7. (rw)
40  *
41  * In addition to these platform device attributes the driver
42  * registers itself in the Linux backlight control subsystem and is
43  * available to userspace under /sys/class/backlight/fujitsu-laptop/.
44  *
45  * Hotkeys present on certain Fujitsu laptops (eg: the S6xxx series) are
46  * also supported by this driver.
47  *
48  * This driver has been tested on a Fujitsu Lifebook S6410, S7020 and
49  * P8010.  It should work on most P-series and S-series Lifebooks, but
50  * YMMV.
51  *
52  * The module parameter use_alt_lcd_levels switches between different ACPI
53  * brightness controls which are used by different Fujitsu laptops.  In most
54  * cases the correct method is automatically detected. "use_alt_lcd_levels=1"
55  * is applicable for a Fujitsu Lifebook S6410 if autodetection fails.
