Subject: [PATCHv9 3/8] iommu/arm-smmu: Move non-strict mode to use io_pgtable_domain_attr
Date: Mon, 23 Nov 2020 22:35:56 +0530 [thread overview]
Message-ID: <47f8e9760a7fba8b58ea89c9add96f5615f97014.1606150259.git.saiprakash.ranjan@codeaurora.org> (raw)
In-Reply-To: <cover.1606150259.git.saiprakash.ranjan@codeaurora.org>
Now that we have a struct io_pgtable_domain_attr with quirks,
use that for non_strict mode as well thereby removing the need
for more members of arm_smmu_domain in the future.
