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.
