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 | * | |
20b93734 JW |
45 | * Hotkeys present on certain Fujitsu laptops (eg: the S6xxx series) are |
46 | * also supported by this driver. | |
47 | * | |
0e6a66e9 JW |
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. | |
20b93734 JW |
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. | |
56 | * | |
