From d23f028a4ddce8b783c212bfe911d1d307ff3617 Mon Sep 17 00:00:00 2001 From: Steve Glendinning Date: Tue, 27 Jan 2009 06:51:11 +0000 Subject: smsc911x: add external phy detection overrides On LAN9115/LAN9117/LAN9215/LAN9217, external phys are supported. These are usually indicated by a hardware strap which sets an "external PHY detected" bit in the HW_CFG register. In some cases it is desirable to override this hardware strap and force use of either the internal phy or an external PHY. This patch adds SMSC911X_FORCE_INTERNAL_PHY and SMSC911X_FORCE_EXTERNAL_PHY flags so a platform can indicate this preference via its platform_data.
