+  performed after restarting.
+
+  When the power-off handler is called, the ethernet PHY LED2 ouptut is
+  set to OFF. If the restart command is executed then the PHY LED2 output
+  is asserted to ON.

Thanks for the patch.

DT bindings need to be CC'd to devicetree@vger.kernel.org and to
Rob Herring. Also please Cc me (sre@kernel.org). I will not merge
this without an explicit Acked-by from Rob.
