-From: Tim Harvey <tharvey@gateworks.com>
-Subject: [PATCH] sky2: allow mac to come from dt
-
-The driver reads the mac address from the device registers which would
-need to have been programmed by the bootloader. This patch adds
-the ability to pull the mac from devicetree via the aliases/sky2 node.
