From e81c0aba9a5e56d6e9b25a669c582827f999302f Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Thu, 13 Oct 2011 14:55:59 -0500 Subject: [PATCH] fm-eth: Don't mark the MAC we use for MDIO as disabled in device tree FM1-DTSEC1's MAC was being marked as disabled if the port was not configured based on the SoC configuration. However we utilize the MAC interface for MDIO and thus should NOT mark it disabled.
