| 3 | Optional properties for child nodes: |
| 4 | - label : The label for this LED. If omitted, the label is |
| 5 | taken from the node name (excluding the unit address). |
| 6 | |
| 7 | - linux,default-trigger : This parameter, if present, is a |
| 8 | string defining the trigger assigned to the LED. Current triggers are: |
| 9 | "backlight" - LED will act as a back-light, controlled by the framebuffer |
| 10 | system |
| 11 | "default-on" - LED will turn on (but for leds-gpio see "default-state" |
| 12 | property in Documentation/devicetree/bindings/gpio/led.txt) |
| 13 | "heartbeat" - LED "double" flashes at a load average based rate |
| 14 | "ide-disk" - LED indicates disk activity |
| 15 | "timer" - LED flashes at a fixed, configurable rate |
| 16 | |
| 17 | Examples: |
| 18 | |
| 19 | system-status { |
| 20 | label = "Status"; |
| 21 | linux,default-trigger = "heartbeat"; |
| 22 | ... |
| 23 | }; |
