From 1f69dcfdaef84614b3ac7ac113d1b9a286afb9a0 Mon Sep 17 00:00:00 2001 From: Valentine Barshak Date: Tue, 2 Oct 2007 00:12:09 +1000 Subject: [PATCH] [POWERPC] 4xx: Add RGMII support for Sequoia 440EPx This adds RGMII support to Sequoia DTS and sets correct phy-mode for EMACs. According to Sequoia datasheet, both ethernet ports are connected to RGMII interface, while ZMII is used only for MDIO.
