Subject: [PATCH 2/5] iommu/arm-smmu: add IOMMU_CAP_BYPASS to the ARM SMMU driver
Date: Wed, 19 Jul 2017 15:03:55 +0530 [thread overview]
Message-ID: <1500456838-18405-3-git-send-email-anup.patel@broadcom.com> (raw)
In-Reply-To: <1500456838-18405-1-git-send-email-anup.patel@broadcom.com>
The ARM SMMUv1 and SMMUv2 support bypassing transactions for
which domain is not configured. The patch adds corresponding
IOMMU capability to advertise this fact.
