Subject: [PATCH 12/13] mmc: atmel-mci: use endian agnostic IO
Date: Wed, 18 Mar 2015 15:53:11 +0000	[thread overview]
Message-ID: <1426693992-31163-13-git-send-email-ben.dooks@codethink.co.uk> (raw)
In-Reply-To: <1426693992-31163-1-git-send-email-ben.dooks@codethink.co.uk>

Change the __raw IO functions to endian agnostic relaxed ones to allow
the driver to function on big endian ARM systems.
