   4           Say Y to enable Linux LED support.  This allows control of supported
   5           LEDs from both userspace and optionally, by kernel events (triggers).

   7           This is not related to standard keyboard LEDs which are controlled
   8           via the input system.

 123         help
 124           This driver makes the mail LED accessible from userspace
 125           programs through the leds subsystem. This LED have three
 126           known mode: off, blink at 0.5Hz and blink at 1Hz.
 127
 128           The driver supports two kinds of interface: using ledtrig-timer
 129           or through /sys/class/leds/clevo::mail/brightness. As this LED
 130           cannot change it's brightness it blinks instead. The brightness
 131           value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
 132           blink at 1Hz.
 133
 134           This module can drive the mail LED for the following notebooks:
 135
 136                 Clevo D400P
 137                 Clevo D410J

 139                 Clevo D400V/D470V (not tested, but might work)
 140                 Clevo M540N
 141                 Clevo M5x0N (not tested, but might work)
 142                 Positivo Mobile (Clevo M5x0V)

 144           If your model is not listed here you can try the "nodetect"
 145           module paramter.

 147           To compile this driver as a module, choose M here: the
 148           module will be called leds-clevo-mail.
