  1 menuconfig 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.

 11 config 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.
 19 
 20           If unsure, say Y.
 21 
 22 config 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.
 35 
 36 config 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.
 43 
 44 config 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 
 52 config 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 
 61 config 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 
 70 config 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 
 80 config 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 
 93 config 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.

100 comment "iptables trigger is under Netfilter config (LED target)"
101         depends on LEDS_TRIGGERS
102 
103 config 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 
111 config 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 
119 config 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.
