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.
