Atsushi Nemoto 891c668b90 [PATCH] LED: add LED heartbeat trigger
Add an LED trigger acts like a heart beat.  This can be used as a
replacement of CONFIG_HEARTBEAT code exists in some arch's timer code.

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.

config LEDS_CORGI
tristate "LED Support for the Sharp SL-C7x0 series"
depends LEDS_CLASS && PXA_SHARP_C7xx
help
This option enables support for the LEDs on Sharp Zaurus
SL-C7x0 series (C700, C750, C760, C860).
config LEDS_LOCOMO
tristate "LED Support for Locomo device"
depends LEDS_CLASS && SHARP_LOCOMO
help
This option enables support for the LEDs on Sharp Locomo.
Zaurus models SL-5500 and SL-5600.
config LEDS_SPITZ
tristate "LED Support for the Sharp SL-Cxx00 series"
depends LEDS_CLASS && PXA_SHARP_Cxx00
help
This option enables support for the LEDs on Sharp Zaurus
SL-Cxx00 series (C1000, C3000, C3100).
config LEDS_IXP4XX
tristate "LED Support for GPIO connected LEDs on IXP4XX processors"
depends LEDS_CLASS && ARCH_IXP4XX
help
This option enables support for the LEDs connected to GPIO
outputs of the Intel IXP4XX processors. To be useful the
particular board must have LEDs and they must be connected
to the GPIO lines. If unsure, say Y.
config LEDS_TOSA
tristate "LED Support for the Sharp SL-6000 series"
depends LEDS_CLASS && PXA_SHARPSL
help
This option enables support for the LEDs on Sharp Zaurus
SL-6000 series.
config LEDS_S3C24XX
tristate "LED Support for Samsung S3C24XX GPIO LEDs"
depends on LEDS_CLASS && ARCH_S3C2410
help
This option enables support for LEDs connected to GPIO lines
on Samsung S3C24XX series CPUs, such as the S3C2410 and S3C2440.
config LEDS_AMS_DELTA
tristate "LED Support for the Amstrad Delta (E3)"
depends LEDS_CLASS && MACH_AMS_DELTA
help
This option enables support for the LEDs on Amstrad Delta (E3).
comment "LED Triggers"
config LEDS_TRIGGERS
bool "LED Trigger support"
depends NEW_LEDS
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 LEDS_TRIGGERS
help
This allows LEDs to be controlled by a programmable timer
via sysfs. If unsure, say Y.
config LEDS_TRIGGER_IDE_DISK
bool "LED IDE Disk Trigger"
depends LEDS_TRIGGERS && BLK_DEV_IDEDISK
help
This allows LEDs to be controlled by IDE disk activity.
If unsure, say Y.
config LEDS_TRIGGER_HEARTBEAT
tristate "LED Heartbeat Trigger"
depends 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.
