From: Daniel Mack Date: Wed, 26 Sep 2012 07:24:27 +0000 (+0000) Subject: net: ti cpsw ethernet: allow reading phy interface mode from DT X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=d7559982701ac500662b2e8e150ff34f7faf0281;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git net: ti cpsw ethernet: allow reading phy interface mode from DT Allow users to specify the phy interface of the CPSW slaves. The new node parameter is called "phy_if_mode" and is optional. The original behaviour of the driver is preserved when not given.
