  105. This driver makes the mail LED accessible from userspace
  106. programs through the leds subsystem. This LED have three
  107. known mode: off, blink at 0.5Hz and blink at 1Hz.
  108. The driver supports two kinds of interface: using ledtrig-timer
  109. or through /sys/class/leds/clevo::mail/brightness. As this LED
  110. cannot change it's brightness it blinks instead. The brightness
  111. value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
  112. blink at 1Hz.
  113. This module can drive the mail LED for the following notebooks:
  114. Clevo D400P
  115. Clevo D410J
  116. Clevo D410V
