 125         help
 126           This driver makes the mail LED accessible from userspace
 127           programs through the leds subsystem. This LED have three
 128           known mode: off, blink at 0.5Hz and blink at 1Hz.
 129
 130           The driver supports two kinds of interface: using ledtrig-timer
 131           or through /sys/class/leds/clevo::mail/brightness. As this LED
 132           cannot change it's brightness it blinks instead. The brightness
 133           value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
 134           blink at 1Hz.
 135
 136           This module can drive the mail LED for the following notebooks:
 137
 138                 Clevo D410J
 139                 Clevo D410V
 140                 Clevo D400V/D470V (not tested, but might work)
 141                 Clevo M540N
 142                 Clevo M5x0N (not tested, but might work)
 143                 Positivo Mobile (Clevo M5x0V)
 144
 145           To compile this driver as a module, choose M here: the
 146           module will be called leds-clevo-mail.
