From fc8f5aded1cf9f5505c55694b36174621c7ac88c Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 12 Nov 2012 17:03:47 +0100 Subject: net: mvmdio: new Marvell MDIO driver This patch adds a separate driver for the MDIO interface of the Marvell Ethernet controllers. There are two reasons to have a separate driver rather than including it inside the MAC driver itself: *) The MDIO interface is shared by all Ethernet ports, so a driver must guarantee non-concurrent accesses to this MDIO interface. The most logical way is to have a separate driver that handles this single MDIO interface, used by all Ethernet ports. *) The MDIO interface is the same between the existing mv643xx_eth driver and the new mvneta driver. Even though it is for now only used by the mvneta driver, it will in the future be used by the mv643xx_eth driver as well. Signed-off-by: Thomas Petazzoni Acked-by: David S.
