From 116b8e164116be537f50cdcce84d80be0facd0cf Mon Sep 17 00:00:00 2001 From: Jacek Anaszewski Date: Thu, 26 Mar 2015 07:03:09 -0700 Subject: DT: leds: Add uniqueness requirement for 'label' property. Label is used for naming LED class devices. Since ePAPR doesn't require uniqueness for label properties, it has to be explicitly required in the LEDs common bindings documentation.
