From 08932d81961b1c57870949d069ce2dad235da443 Mon Sep 17 00:00:00 2001 From: Ryan Mallon Date: Wed, 11 Jan 2012 09:58:30 +1100 Subject: ep93xx: Configure GPIO ports in core code Move the pinmux setting of the EP93xx GPIOs to the core code. This removes the need for the GPIO driver to have access to the system controller registers.
