Subject: [PATCH 06/13] ARM: dts: dra7-evm: Add CAN support
Date: Mon, 8 Sep 2014 17:10:35 +0300	[thread overview]
Message-ID: <1410185442-907-7-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1410185442-907-1-git-send-email-rogerq@ti.com>

The board has 2 CAN ports but only the first one can be used.
Enable the first CAN port.

The second one cannot be used without hardware modification
so we don't enable the second port.
