From: Vince Bridgers Date: Thu, 12 Feb 2015 16:47:33 +0000 (-0600) Subject: net: eth: altera: Change access ports to mdio for all xMII applications X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a923fc730fdbbf079eadfe2b9a1644971bd95793;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
