Subject: [PATCH 06/13] ARM: at91: PIT: make IO endian agnostic
Date: Wed, 18 Mar 2015 15:53:05 +0000	[thread overview]
Message-ID: <1426693992-31163-7-git-send-email-ben.dooks@codethink.co.uk> (raw)
In-Reply-To: <1426693992-31163-1-git-send-email-ben.dooks@codethink.co.uk>

Fix the use of __raw IO accessor with the readl/writel_relaxed versions
to allow the code to be used on a system running in big endian.
