| Common leds properties. |
| |
| Optional properties for child nodes: |
| - label : The label for this LED. If omitted, the label is |
| taken from the node name (excluding the unit address). |
| |
| - linux,default-trigger : This parameter, if present, is a |
| string defining the trigger assigned to the LED. Current triggers are: |
| "backlight" - LED will act as a back-light, controlled by the framebuffer |
| system |
| "default-on" - LED will turn on (but for leds-gpio see "default-state" |
| property in Documentation/devicetree/bindings/gpio/led.txt) |
| "heartbeat" - LED "double" flashes at a load average based rate |
| "ide-disk" - LED indicates disk activity |
| "timer" - LED flashes at a fixed, configurable rate |
| |
| - max-microamp : maximum intensity in microamperes of the LED |
| - flash-max-microamp : maximum intensity in microamperes of the |
| flash LED; it is mandatory if the LED should |
| support the flash mode |
| - flash-timeout-microsec : timeout in microseconds after which the flash |
| LED is turned off |
| |
| |
| Examples: |
| |
| system-status { |
| label = "Status"; |
| linux,default-trigger = "heartbeat"; |
| ... |
| }; |
| |
| camera-flash { |
| label = "Flash"; |
| max-microamp = <50000>; |
| flash-max-microamp = <320000>; |
| flash-timeout-microsec = <500000>; |
| } |
