Subject: [PATCHv4 5/6] iommu: arm-smmu-impl: Use table to list QCOM implementations
Date: Fri, 11 Sep 2020 14:28:14 +0000	[thread overview]
Message-ID: <010101747d9117d8-644f919c-0d21-4bb3-b969-96afec1a1ef5-000000@us-west-2.amazonses.com> (raw)
In-Reply-To: <cover.1599832685.git.saiprakash.ranjan@codeaurora.org>

Use table and of_match_node() to match qcom implementation
instead of multiple of_device_compatible() calls for each
QCOM SMMU implementation.
