From 3f518509dedc99f0b755d2ce68d24f610e3a005a Mon Sep 17 00:00:00 2001 From: Marcin Wojtas Date: Thu, 10 Jul 2014 16:52:13 -0300 Subject: ethernet: Add new driver for Marvell Armada 375 network unit This commit adds a new network driver for the network controller in Marvell Armada 375 SoC. Given the controller is very different from the ones in the other Marvell SoCs that use the mv643xx_eth (Kirkwood, Orion, Discovery) and mvneta (Armada 370/38x/XP) drivers, a new driver is needed.
