    Subject[PATCH v7 3/6] dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU
    Date
    Every Qcom Adreno GPU has an embedded SMMU for its own use. These
    devices depend on unique features such as split pagetables,
    different stall/halt requirements and other settings. Identify them
    with a compatible string so that they can be identified in the
    arm-smmu implementation specific code.
