menu "LED devices"
	depends on HAS_IOMEM

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 on 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.

	  on Samsung S3C24XX series CPUs, such as the S3C2410 and S3C2440.

config LEDS_AMS_DELTA
	tristate "LED Support for the Amstrad Delta (E3)"
	depends on LEDS_CLASS && MACH_AMS_DELTA
	help
	  This option enables support for the LEDs on Amstrad Delta (E3).

config LEDS_NET48XX
	tristate "LED Support for Soekris net48xx series Error LED"
	depends on LEDS_CLASS && SCx200_GPIO
	help
	  This option enables support for the Soekris net4801 and net4826 error
	  LED.

config LEDS_WRAP
	tristate "LED Support for the WRAP series LEDs"
	depends on LEDS_CLASS && SCx200_GPIO
	help
	  This option enables support for the PCEngines WRAP programmable LEDs.

config LEDS_H1940
	tristate "LED Support for iPAQ H1940 device"
	depends LEDS_CLASS && ARCH_H1940
	help
	  This option enables support for the LEDs on the h1940.

config LEDS_COBALT
	tristate "LED Support for Cobalt Server front LED"
	depends on LEDS_CLASS && MIPS_COBALT

config LEDS_GPIO
	tristate "LED Support for GPIO connected LEDs"
	depends on LEDS_CLASS && GENERIC_GPIO
	help
	  This option enables support for the LEDs connected to GPIO
	  outputs. To be useful the particular board must have LEDs
	  and they must be connected to the GPIO lines.

comment "LED Triggers"

config LEDS_TRIGGERS
	bool "LED Trigger support"
	depends on NEW_LEDS
