Subject: [PATCH 0/3] omap: iovmm: Fix IOVMM check for fixed 'da'
Date: Tue, 8 Mar 2011 14:46:02 +0200 [thread overview]
Message-ID: <1299588365-2749-1-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.

omap3: change ISP's IOMMU da_start address
omap: iovmm: don't check 'da' to set IOVMF_DA_FIXED/IOVMF_DA_ANON
flags
