122 tristate "Mail LED on Clevo notebook (EXPERIMENTAL)"
123 depends on LEDS_CLASS && X86 && SERIO_I8042 && DMI && EXPERIMENTAL
125 This driver makes the mail LED accessible from userspace
126 programs through the leds subsystem. This LED have three
127 known mode: off, blink at 0.5Hz and blink at 1Hz.
129 The driver supports two kinds of interface: using ledtrig-timer
130 or through /sys/class/leds/clevo::mail/brightness. As this LED
131 cannot change it's brightness it blinks instead. The brightness
132 value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
135 This module can drive the mail LED for the following notebooks:
