Subject: [PATCH 6/6] mtd: ofpart: add compatible check for child nodes
Date: Mon, 10 Jun 2013 18:26:54 +0800	[thread overview]
Message-ID: <1370860014-1770-7-git-send-email-josh.wu@atmel.com> (raw)
In-Reply-To: <1370860014-1770-1-git-send-email-josh.wu@atmel.com>

If the child node has compatible property then it is a driver not partition.
