From a409fdd8fe013aa4a4564bedc1f673b9455e64da Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 2 Jun 2010 06:00:27 -0400 Subject: Blackfin: serial: convert to portmux framework Use the new portmux framework to handle the details when possible. Unfortunately, we cannot yet use this in the standalone initialization logic, so we need to keep around the old portmux writes for now.
