leds: Add support for hardware accelerated LED flashing

[net-next-2.6.git] / drivers / leds / Kconfig

menuconfig NEW_LEDS
	bool "LED Support"
	depends on HAS_IOMEM
	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"
	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.

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.

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

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

comment "LED Triggers"

config LEDS_TRIGGERS
	bool "LED Trigger support"
	help
	  This option enables trigger support for the leds class.
	  These triggers allow kernel events to drive the LEDs and can
	  be configured via sysfs. If unsure, say Y.

config LEDS_TRIGGER_TIMER
	tristate "LED Timer Trigger"
	depends on LEDS_TRIGGERS
	help
	  This allows LEDs to be controlled by a programmable timer
	  via sysfs. Some LED hardware can be programmed to start
	  blinking the LED without any further software interaction.
	  For more details read Documentation/leds-class.txt.

	  If unsure, say Y.

config LEDS_TRIGGER_IDE_DISK
	bool "LED IDE Disk Trigger"
	depends on LEDS_TRIGGERS && BLK_DEV_IDEDISK

	  If unsure, say Y.

config LEDS_TRIGGER_HEARTBEAT
	tristate "LED Heartbeat Trigger"
	depends on LEDS_TRIGGERS
	help
	  This allows LEDs to be controlled by a CPU load average.
	  The flash frequency is a hyperbolic function of the 1-minute
	  load average.
	  If unsure, say Y.
