From a923fc730fdbbf079eadfe2b9a1644971bd95793 Mon Sep 17 00:00:00 2001 From: Vince Bridgers Date: Thu, 12 Feb 2015 10:47:33 -0600 Subject: [PATCH] net: eth: altera: Change access ports to mdio for all xMII applications Change use of Altera TSE's MDIO access from phy 0 registers to phy 1 registers. This allows support for GMII, MII, RGMII, and SGMII designs where the external PHY is always accesible through Altera TSE's MDIO phy 1 registers and Altera's PCS is accessible through MDIO phy 0 registers for SGMII applications.
