Subject:    [PATCH 15/23] iommu/tegra: smmu: Calculate ASID register offset by ID
From:       hdoyu () nvidia ! com (Hiroshi Doyu)
Date:       2013-06-26 9:28:18
Message-ID: 1372238906-9346-16-git-send-email-hdoyu () nvidia ! com

Calculate ASID register offset by ID so that we can get rid of SoC
specific MACROs. This is needed for the unified SMMU driver over Tegra
SoCs.
