* [PATCH] LED: add LED trigger tupportRichard Purdie2006-03-311-0/+13
| | | | | | | | | | | | Add support for LED triggers to the LED subsystem. "Triggers" are events which change the state of an LED. Two kinds of trigger are available, simple ones which can be added to exising code with minimum disruption and complex ones for implementing new or more complex functionality.
