Subject: [PATCH 17/29] of: make OFDEVICE a user selectable option
Date: Tue, 26 Feb 2013 21:18:44 +0100	[thread overview]
Message-ID: <1361909936-2665-18-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1361909936-2665-1-git-send-email-s.hauer@pengutronix.de>

OFDEVICE decides whether or not we compile in support for probing
devices from the devicetree. Let the user decide this explicitly.
This makes the oftree, of_node and of_property commands independent
of devicetree device support since being able to manipulate
devicetrees has nothing to do with probing devices from the devicetree.
