320 This driver makes the mail LED accessible from userspace
321 programs through the leds subsystem. This LED have three
322 known mode: off, blink at 0.5Hz and blink at 1Hz.
323
Márton Németh92e015c2007-10-31 15:09:05 +0100324 The driver supports two kinds of interface: using ledtrig-timer
325 or through /sys/class/leds/clevo::mail/brightness. As this LED
326 cannot change it's brightness it blinks instead. The brightness
327 value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
328 blink at 1Hz.
