From 004ea683d96ff51131789e78a3de7dafcdbf912d Mon Sep 17 00:00:00 2001 From: Grant Erickson Date: Wed, 9 Jul 2008 01:03:06 +1000 Subject: ibm_newemac: Add MII mode support to the EMAC RGMII bridge. This patch adds support to the RGMII handler in the EMAC driver for the MII PHY mode such that device tree entries of the form `phy-mode = "mii";' are recognized and handled appropriately. While logically, in software, "gmii" and "mii" modes are the same, they are wired differently, so it makes sense to allow DTS authors to specify each explicitly.
