1menuconfig LEDS_TRIGGERS
  2	bool "LED Trigger support"
  3	depends on LEDS_CLASS
  4	help
  5	  This option enables trigger support for the leds class.
  6	  These triggers allow kernel events to drive the LEDs and can
  7	  be configured via sysfs. If unsure, say Y.

 11config LEDS_TRIGGER_TIMER
 12	tristate "LED Timer Trigger"
 13	depends on LEDS_TRIGGERS
 14	help
 15	  This allows LEDs to be controlled by a programmable timer
 16	  via sysfs. Some LED hardware can be programmed to start
 17	  blinking the LED without any further software interaction.
 18	  For more details read Documentation/leds/leds-class.txt.

 22config LEDS_TRIGGER_ONESHOT
 23	tristate "LED One-shot Trigger"
 24	depends on LEDS_TRIGGERS
 25	help
 26	  This allows LEDs to blink in one-shot pulses with parameters
 27	  controlled via sysfs.  It's useful to notify the user on
 28	  sporadic events, when there are no clear begin and end trap points,
 29	  or on dense events, where this blinks the LED at constant rate if
 30	  rearmed continuously.
 31
 32	  It also shows how to use the led_blink_set_oneshot() function.
 33
 34	  If unsure, say Y.

 36config LEDS_TRIGGER_DISK
 37	bool "LED Disk Trigger"
 38	depends on IDE_GD_ATA || ATA
 39	depends on LEDS_TRIGGERS
 40	help
 41	  This allows LEDs to be controlled by disk activity.
 42	  If unsure, say Y.

 44config LEDS_TRIGGER_MTD
 45	bool "LED MTD (NAND/NOR) Trigger"
 46	depends on MTD
 47	depends on LEDS_TRIGGERS
 48	help
 49	  This allows LEDs to be controlled by MTD activity.
 50	  If unsure, say N.
 51
 52config LEDS_TRIGGER_HEARTBEAT
 53	tristate "LED Heartbeat Trigger"
 54	depends on LEDS_TRIGGERS
 55	help
 56	  This allows LEDs to be controlled by a CPU load average.
 57	  The flash frequency is a hyperbolic function of the 1-minute
 58	  load average.
 59	  If unsure, say Y.
 60
 61config LEDS_TRIGGER_BACKLIGHT
 62	tristate "LED backlight Trigger"
 63	depends on LEDS_TRIGGERS
 64	help
 65	  This allows LEDs to be controlled as a backlight device: they
 66	  turn off and on when the display is blanked and unblanked.
 67
 68	  If unsure, say N.
 69
 70config LEDS_TRIGGER_CPU
 71	bool "LED CPU Trigger"
 72	depends on LEDS_TRIGGERS
 73	help
 74	  This allows LEDs to be controlled by active CPUs. This shows
 75	  the active CPUs across an array of LEDs so you can see which
 76	  CPUs are active on the system at any given moment.
 77
 78	  If unsure, say N.
 79
 80config LEDS_TRIGGER_GPIO
 81	tristate "LED GPIO Trigger"
 82	depends on LEDS_TRIGGERS
 83	depends on GPIOLIB || COMPILE_TEST
 84	help
 85	  This allows LEDs to be controlled by gpio events. It's good
 86	  when using gpios as switches and triggering the needed LEDs
 87	  from there. One use case is n810's keypad LEDs that could
 88	  be triggered by this trigger when user slides up to show
 89	  keypad.
 90
 91	  If unsure, say N.
 92
 93config LEDS_TRIGGER_DEFAULT_ON
 94	tristate "LED Default ON Trigger"
 95	depends on LEDS_TRIGGERS
 96	help
 97	  This allows LEDs to be initialised in the ON state.
 98	  If unsure, say Y.

103config LEDS_TRIGGER_TRANSIENT
104	tristate "LED Transient Trigger"
105	depends on LEDS_TRIGGERS
106	help
107	  This allows one time activation of a transient state on
108	  GPIO/PWM based hardware.
109	  If unsure, say Y.
110
111config LEDS_TRIGGER_CAMERA
112	tristate "LED Camera Flash/Torch Trigger"
113	depends on LEDS_TRIGGERS
114	help
115	  This allows LEDs to be controlled as a camera flash/torch device.
116	  This enables direct flash/torch on/off by the driver, kernel space.
117	  If unsure, say Y.
118
119config LEDS_TRIGGER_PANIC
120	bool "LED Panic Trigger"
121	depends on LEDS_TRIGGERS
122	help
123	  This allows LEDs to be configured to blink on a kernel panic.
124	  Enabling this option will allow to mark certain LEDs as panic indicators,
125	  allowing to blink them on a kernel panic, even if they are set to
126	  a different trigger.
127	  If unsure, say Y.
