From 6d06c4e318382a5c0bc1e2243b77f58d5ecd88ea Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Tue, 13 Aug 2013 16:53:15 +0200 Subject: of_property command: allow to set phandles With this properties with phandles can be created. A phandle is created when cells are parsed (in '<' '>') and a cell does not begin with a digit. The phandles can be specified either by alias or by full path.
