From fd9962352105f19711d55cc2caaf75b2e201598b Mon Sep 17 00:00:00 2001 From: Jamie Iles Date: Fri, 20 May 2011 00:40:17 -0600 Subject: [PATCH] basic_mmio_gpio: convert to non-__raw* accessors The __raw_* accessors don't include memory barriers and can cause problems when writes get stuck in write buffers.
