Subject: [PATCH 04/17] ARM: am335x phytec phyCORE: Switch to devicetree probe support
Date: Tue, 26 Nov 2013 17:45:54 +0100	[thread overview]
Message-ID: <1385484367-15366-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1385484367-15366-1-git-send-email-s.hauer@pengutronix.de>

This switches the am335x Phytec phyCORE to devicetree probe support.
For now we use a linked in dtb.
