-From: Anton Vorontsov <avorontsov@ru.mvista.com>
-Date: Wed, 5 Mar 2008 14:52:26 +0300
-Subject: [PATCH] AR7/cpmac: convert to new fixed phy infrastructure, now for real
-
-This patch converts platform code to register fixed phys early.
-cpmac driver modified to blindly accept fixed phy id (that is equal
-to platform device id).
