  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.
  56 *
