From 9616a75505be9b87f9625c4d87d8b07a45ddad4d Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 13 Mar 2009 13:48:46 -0700 Subject: [PATCH] emac: Fix clock control for 405EX and 405EXr chips The EMAC variant in the 405EX and 405EXr chips needs the "440EP" type clock control workaround to avoid lockups of the Rx side during reset.
