[PATCHv5 5/6] iommu: arm-smmu-impl: Use table to list QCOM implementations

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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