23 tristate "LED One-shot Trigger"
25 This allows LEDs to blink in one-shot pulses with parameters
53 The flash frequency is a hyperbolic function of the 1-minute
61 turn off and on when the display is blanked and unblanked.
113 This enables direct flash/torch on/off by the driver, kernel space.
146 When build as a module this driver will be called ledtrig-tty.
152 Turn LEDs on when there is input (/dev/input/event*) activity and turn
153 them back off again after there has been no activity for 5 seconds.
