Subject: [PATCH 2/3] omap3: change ISP's IOMMU da_start address
Date: Tue,  8 Mar 2011 14:46:04 +0200	[thread overview]
Message-ID: <1299588365-2749-3-git-send-email-dacohen@gmail.com> (raw)
In-Reply-To: <1299588365-2749-1-git-send-email-dacohen@gmail.com>

ISP doesn't consider 0x0 as a valid address, so it should explicitly
exclude first page from allowed 'da' range.
