| 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. |

| 37 | bool "LED IDE Disk Trigger" |
| 38 | depends on IDE_GD_ATA |
| 39 | depends on LEDS_TRIGGERS |
| 40 | help |
| 41 | This allows LEDs to be controlled by IDE disk activity. |
| 42 | If unsure, say Y. |
| 43 | |
| 44 | config LEDS_TRIGGER_HEARTBEAT |
| 45 | tristate "LED Heartbeat Trigger" |
| 46 | depends on LEDS_TRIGGERS |
| 47 | help |
| 48 | This allows LEDs to be controlled by a CPU load average. |
| 49 | The flash frequency is a hyperbolic function of the 1-minute |
| 50 | load average. |
| 51 | If unsure, say Y. |
| 52 | |
| 53 | config LEDS_TRIGGER_BACKLIGHT |
| 54 | tristate "LED backlight Trigger" |
| 55 | depends on LEDS_TRIGGERS |
| 56 | help |
| 57 | This allows LEDs to be controlled as a backlight device: they |
| 58 | turn off and on when the display is blanked and unblanked. |
| 59 | |
| 60 | If unsure, say N. |
| 61 | |
| 62 | config LEDS_TRIGGER_CPU |
| 63 | bool "LED CPU Trigger" |
| 64 | depends on LEDS_TRIGGERS |
| 65 | help |
| 66 | This allows LEDs to be controlled by active CPUs. This shows |
| 67 | the active CPUs across an array of LEDs so you can see which |
| 68 | CPUs are active on the system at any given moment. |
| 69 | |
| 70 | If unsure, say N. |

| Kim, Milo | f07fb52 | 2013-02-20 00:36:01 -0800 | [diff] [blame] | 76 | help |
| 77 | This allows LEDs to be controlled by gpio events. It's good |
| 78 | when using gpios as switches and triggering the needed LEDs |
| 79 | from there. One use case is n810's keypad LEDs that could |
| 80 | be triggered by this trigger when user slides up to show |
| 81 | keypad. |
| 82 | |
| 83 | If unsure, say N. |

| 85 | config LEDS_TRIGGER_DEFAULT_ON |
| 86 | tristate "LED Default ON Trigger" |
| 87 | depends on LEDS_TRIGGERS |
| 88 | help |
| 89 | This allows LEDs to be initialised in the ON state. |
| 90 | If unsure, say Y. |

| 95 | config LEDS_TRIGGER_TRANSIENT |
| 96 | tristate "LED Transient Trigger" |
| 97 | depends on LEDS_TRIGGERS |
| 98 | help |
| 99 | This allows one time activation of a transient state on |
| 100 | GPIO/PWM based hardware. |

| 104 | tristate "LED Camera Flash/Torch Trigger" |
| 105 | depends on LEDS_TRIGGERS |
| 106 | help |
| 107 | This allows LEDs to be controlled as a camera flash/torch device. |
| 108 | This enables direct flash/torch on/off by the driver, kernel space. |
| 109 | If unsure, say Y. |
