Subject: [PATCH v2 2/3] omap3: change ISP's IOMMU da_start address
Date: Tue, 8 Mar 2011 22:15:15 +0200 [thread overview]
Message-ID: <1299615316-17512-3-git-send-email-dacohen@gmail.com> (raw)
In-Reply-To: <1299615316-17512-1-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.
