From 01999873a455fe9104e91820c72849e608239928 Mon Sep 17 00:00:00 2001 From: Dale Farnsworth Date: Fri, 27 Jan 2006 01:18:01 -0700 Subject: [PATCH] [PATCH] mv643xx_eth: Clean up platform_data configuration We shouldn't expose the hardware register contents in platform_data. The only things we allow the user to configure are autoneg, speed, and duplex. Add specific platform_data fields for these values and remove the registers configs.
