Subject: [PATCH v2 0/3] omap: iovmm: Fix IOVMM check for fixed 'da'
Date: Tue, 8 Mar 2011 22:15:13 +0200 [thread overview]
Message-ID: <1299615316-17512-1-git-send-email-dacohen@gmail.com> (raw)
IOVMM driver checks input 'da == 0' when mapping address to determine whether
user wants fixed 'da' or not. At the same time, it doesn't disallow address
0x0 to be used, what creates an ambiguous situation. This patch set moves
fixed 'da' check to the input flags.
It also fixes da_start value for ISP IOMMU instance.
Br,
David Cohen
