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
138	  	Clevo D410V
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)
143
144	  If your model is not listed here you can try the "nodetect"
145	  module paramter.
146
147	  To compile this driver as a module, choose M here: the
148	  module will be called leds-clevo-mail.
