From 5751aa2f248a72c3cec7048cec8dfad33dab0979 Mon Sep 17 00:00:00 2001 From: Nobuhiro Iwamatsu Date: Wed, 23 Nov 2011 21:24:15 +0000 Subject: [PATCH] phy: Add support for SMSC LAN87xx PHYs This adds support for the SMSC LAN87xx PHYs. Following PHYs can be used by set CONFIG_PHY_SMSC to config. - SMSC LAN8700 - SMSC LAN8710/LAN8720 - SMSC LAN8710/LAN8720 A setup of PHY was copied from linux kenrel.
