Subject: [[PATCH v2] 11/11] hwrng: exynos - fixup IO accesors
Date: Tue, 21 Jun 2016 11:20:32 +0100
Message-ID: <1466504432-24187-12-git-send-email-ben.dooks@codethink.co.uk> (raw)
In-Reply-To: <1466504432-24187-1-git-send-email-ben.dooks@codethink.co.uk>

The __raw IO functions are not endian safe, so use the readl_relaxed
and writel_relaxed versions of these.
