  30 /*
  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.
