From 1577ecef766650a57fceb171acee2b13cbfaf1d3 Mon Sep 17 00:00:00 2001 From: Andy Fleming Date: Wed, 4 Feb 2009 16:42:12 -0800 Subject: netdev: Merge UCC and gianfar MDIO bus drivers The MDIO bus drivers for the UCC and gianfar ethernet controllers are essentially the same. There's no reason to duplicate that much code. Signed-off-by: Andy Fleming Signed-off-by: David S.
