Message-ID: <1423759653-5023-1-git-send-email-vbridger@opensource.altera.com> Date: Thu, 12 Feb 2015 10:47:33 -0600 From: Vince Bridgers <vbridger@...nsource.altera.com> To: <netdev@...r.kernel.org>, <nios2-dev@...ts.rocketboards.org>, <linux-kernel@...r.kernel.org> CC: <vbridger@...era.com>, <vbridger@...nsource.altera.com>, <kailng@...era.com>, <dwesterg@...il.com> Subject: [PATCH net] 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.
