config NEW_LEDS
	bool "LED Support"
	help
	  Say Y to enable Linux LED support.  This allows control of supported
	  LEDs from both userspace and optionally, by kernel events (triggers).

	  This is not related to standard keyboard LEDs which are controlled
	  via the input system.

config LEDS_CLASS
	tristate "LED Class Support"
	depends NEW_LEDS
	help
	  This option enables the led sysfs class in /sys/class/leds.  You'll
	  need this to do anything useful with LEDs.  If unsure, say N.
