config LEDS_CLEVO_MAIL
	tristate "Mail LED on Clevo notebook (EXPERIMENTAL)"
	depends on LEDS_CLASS && X86 && SERIO_I8042 && DMI && EXPERIMENTAL
	help
	  This driver makes the mail LED accessible from userspace
	  programs through the leds subsystem. This LED have three
	  known mode: off, blink at 0.5Hz and blink at 1Hz.

	  The driver supports two kinds of interface: using ledtrig-timer
	  or through /sys/class/leds/clevo::mail/brightness. As this LED
	  cannot change it's brightness it blinks instead. The brightness
	  value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
	  blink at 1Hz.

	  This module can drive the mail LED for the following notebooks:

	  	Clevo D400P
	  	Clevo D410J
	  	Clevo D410V
	  	Clevo D400V/D470V (not tested, but might work)
	  	Clevo M540N
	  	Clevo M5x0N (not tested, but might work)
	  	Positivo Mobile (Clevo M5x0V)

	  If your model is not listed here you can try the "nodetect"
	  module parameter.

	  To compile this driver as a module, choose M here: the
	  module will be called leds-clevo-mail.
