From 8339ad737316cda3d6246ea6be52e9f78bb63cc4 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 2 Jun 2010 05:56:22 -0400 Subject: Blackfin: bfin_mac: convert to portmux framework Rather than bang MMRs directly, use the new portmux framework to handle the details. While we're doing this, let boards declare the exact list of pins they need in case there is one or two they don't actually have hooked up.
