This property is always a list of phandles to LED nodes (child node of a LED device node). led_device { ... led0: led@0 { ... }; led1: led@1 { ... }; }; consumer { ... leds = <led0>, <led1>; }; > >> >> Optional properties for child nodes: >> - led-sources : List of device current outputs the LED is connected to.

LED properties must be named "leds" in the same way that PWM, clocks or PHY properties are names respectively "pwms", "clocks" and "phys".
