      Fujitsu-laptop update · 20b93734
      Jonathan Woithe authored
      
      Add additional capabilities to the Fujitsu-laptop driver.
      
       * Brightness hotkey actions are sent to userspace. This can be disabled
         using a module parameter if it causes issues with models which handle
         these keys transparently in the BIOS.
      
       * Actions of additional hotkeys found on some Fujitsu models (eg: the
         suspend key and the dedicated "power on passphrase" keys) are broadcast
         to userspace.
      
       * An alternative brightness control method used by some Fujitsu models
         (for example, the S6410) is now supported, enabling software brightness
         controls on models using this method.
      
       * DMI-based module aliases are configured for the S6410 and S7020.
      
       * The current LCD brightness after booting should now be reflected in the
         standard backlight interface sysfs file (previously it was always set to
         0).  The platform brightness sysfs interface has always been fine.
      
      Thanks go to Peter Gruber who provided a significant portion of this code
      and tested various iterations of the patch on his S6410.

      This is driver for Compal Laptop: FL90/IFL90, based on MSI driver.
      
      This driver exports a few files in /sys/devices/platform/compal-laptop/:
       lcd_level - screen brightness: contains a single integer in the range 0..7 (rw)
       wlan - wlan subsystem state: contains 0 or 1 (rw)
       bluetooth - bluetooth subsystem state: contains 0 or 1 (rw)
       raw - raw value taken from embedded controller register (ro)
      
      In addition to these platform device attributes the driver registers itself
      in the Linux backlight control subsystem and is available to userspace under
      /sys/class/backlight/compal-laptop/.
