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.
