/*
 * msi-ec.c - MSI Embedded Controller for laptops support.
 *
 * This driver exports a few files in /sys/devices/platform/msi-laptop:
 *   webcam            Integrated webcam activation
 *   fn_key            Function key location
 *   win_key           Windows key location
 *   battery_mode      Battery health options
 *   cooler_boost      Cooler boost function
 *   shift_mode        CPU & GPU performance modes
 *   fan_mode          FAN performance modes
 *   fw_version        Firmware version
 *   fw_release_date   Firmware release date
 *   cpu/..            CPU related options
 *   gpu/..            GPU related options
 *
 * In addition to these platform device attributes the driver
 * registers itself in the Linux power_supply subsystem and is
 * available to userspace under /sys/class/power_supply/<power_supply>:
 *
 *   charge_control_start_threshold
 *   charge_control_end_threshold
 * 
 * This driver also registers available led class devices for
 * mute, micmute and keyboard_backlight leds
 *
 * This driver might not work on other laptops produced by MSI. Also, and until
 * future enhancements, no DMI data are used to identify your compatibility
