description:
Some LED defined in DT are required by other DT consumers, for example
v4l2 subnode may require privacy or flash LED. Unlike trigger-source
approach which is typically used as 'soft' binding, referencing LED
devices by phandle makes things simpler when 'hard' binding is desired.
Document LED properties that its consumers may define.
