This is worded oddly. The property is 'leds' and it is always a list of
phandles to LED device nodes. It is present in an LED consumer device.
How about:
[...]
A LED consumer device has a 'leds' property. This property is always a list
of phandles to LED nodes (child node of a LED device node).
led_device {

led0: led@0 {
