Subject: [PATCHv5 5/6] iommu: arm-smmu-impl: Use table to list QCOM implementations
Date: Tue, 22 Sep 2020 11:48:18 +0530 [thread overview]
Message-ID: <f2d079d46cee22f09f6eb7e6f874a9eaa786ec2a.1600754909.git.saiprakash.ranjan@codeaurora.org> (raw)
In-Reply-To: <cover.1600754909.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.
Signed-off-by: Sai Prakash Ranjan <saiprakash.ranjan@codeaurora.org>
