132 This driver makes the mail LED accessible from userspace
133 programs through the leds subsystem. This LED have three
134 known mode: off, blink at 0.5Hz and blink at 1Hz.
136 The driver supports two kinds of interface: using ledtrig-timer
137 or through /sys/class/leds/clevo::mail/brightness. As this LED
138 cannot change it's brightness it blinks instead. The brightness
139 value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
142 This module can drive the mail LED for the following notebooks:
147 Clevo D400V/D470V (not tested, but might work)
