  27  * compal-laptop.c - Compal laptop support.
  28  *
  29  * This driver exports a few files in /sys/devices/platform/compal-laptop/:
  30  *   wake_up_XXX   Whether or not we listen to such wake up events (rw)
  31  *
  32  * In addition to these platform device attributes the driver
  33  * registers itself in the Linux backlight control, power_supply, rfkill
  34  * and hwmon subsystem and is available to userspace under:
  35  *
  36  *   /sys/class/backlight/compal-laptop/
  37  *   /sys/class/power_supply/compal-laptop/
  38  *   /sys/class/rfkill/rfkillX/
  39  *   /sys/class/hwmon/hwmonX/
  40  *
  41  * Notes on the power_supply battery interface:
  42  *   - the "minimum" design voltage is *the* design voltage
  43  *   - the ambient temperature is the average battery temperature
  44  *     and the value is an educated guess (see commented code below)
  45  *
  46  *
  47  * This driver might work on other laptops produced by Compal. If you
  48  * want to try it you can pass force=1 as argument to the module which
  49  * will force it to load even when the DMI data doesn't identify the
  50  * laptop as compatible.
  51  *
  52  * Lots of data available at:
  53  * http://service1.marasst.com/Compal/JHL90_91/Service%20Manual/
  54  * JHL90%20service%20manual-Final-0725.pdf
  55  *
  56  *
  57  *
  58  * Support for the Compal JHL90 added by Roald Frederickx
  59  * (roald.frederickx@gmail.com):
  60  * Driver got large revision. Added functionalities: backlight
  61  * power, wake_on_XXX, a hwmon and power_supply interface.
  62  *
  63  * In case this gets merged into the kernel source: I want to dedicate this
  64  * to Kasper Meerts, the awesome guy who showed me Linux and C!
  65  */

  67 /* NOTE: currently the wake_on_XXX, hwmon and power_supply interfaces are
  68  * only enabled on a JHL90 board until it is verified that they work on the
  69  * other boards too.  See the extra_features variable. */
