115 tristate "Mail LED on Clevo notebook (EXPERIMENTAL)"
116 depends on LEDS_CLASS && X86 && SERIO_I8042 && DMI && EXPERIMENTAL
118 This driver makes the mail LED accessible from userspace
119 programs through the leds subsystem. This LED have three
120 known mode: off, blink at 0.5Hz and blink at 1Hz.
122 The driver supports two kinds of interface: using ledtrig-timer
123 or through /sys/class/leds/clevo::mail/brightness. As this LED
124 cannot change it's brightness it blinks instead. The brightness
125 value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
128 This module can drive the mail LED for the following notebooks:
133 Clevo D400V/D470V (not tested, but might work)
135 Clevo M5x0N (not tested, but might work)
