| 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 | * |
Jonathan Woithe | 20b9373 | 2008-06-11 10:14:56 +0930 | [diff] [blame] | 45 | * Hotkeys present on certain Fujitsu laptops (eg: the S6xxx series) are |
| 46 | * also supported by this driver. |
| 47 | * |
Jonathan Woithe | 0e6a66e | 2008-10-09 13:44:40 +0930 | [diff] [blame] | 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. |
Jonathan Woithe | 20b9373 | 2008-06-11 10:14:56 +0930 | [diff] [blame] | 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 | * |
