[PATCH v2 1/2] dt-bindings: iommu: arm,smmu-v3: Add SC8280XP compatible

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

 



The smmu-v3 binding currently doesn't differentiate the SoCs it's
implemented on. This is a poor design choice that may bite in the future,
should any quirks surface.

Add a compatible for the instance found on Qualcomm SC8280XP.
