Date: Tue, 24 Mar 2009 14:47:25 +0800 From: Richard Zhao <linuxzsc@...il.com> To: steve.glendinning@...c.com, netdev@...r.kernel.org Cc: linux-arm-kernel@...ts.arm.linux.org.uk, kernel@...gutronix.de Subject: [PATCH 3/3] smsc911x: add flag SMSC911X_USE_INTERPHY mx31pdk board don't have external PHY, but it wrongly pull up MDIO. So, add flag SMSC911X_USE_INTERPHY to force using internal PHY.
