"ide-disk" - LED indicates IDE disk activity (deprecated),
in new implementations use "disk-activity"
"timer" - LED flashes at a fixed, configurable rate
+ "pattern" - LED alters the brightness for the specified duration with one
+ software timer (requires "led-pattern" property)
+- led-pattern : Array of integers with default pattern for certain triggers.
+ Each trigger may parse this property differently:
+ - one-shot : two numbers specifying delay on and delay off (in ms),
+ - timer : two numbers specifying delay on and delay off (in ms),
+ - pattern : the pattern is given by a series of tuples, of
+ brightness and duration (in ms). The exact format is
+ described in:
+ Documentation/devicetree/bindings/leds/leds-trigger-pattern.txt
- led-max-microamp : Maximum LED supply current in microamperes. This property
can be made mandatory for the board configurations
