From 9acb7da14ebb55b2a9819c34a24f4ce6e99202c4 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 22 Mar 2017 14:15:40 +0100 Subject: [PATCH] net: mvpp2: Read phy-speed from DT to select between 1GB and 2.5GB SGMII Read the "phy-speed" DT property to differentiate between 1 and 2.5GB SGMII operations. Please note that its unclear right now, if this DT property will be accepted in mainline Linux. If not, we need to revisit this code and change it to use the accepted property.
