[PATCH 10/19] dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU
From: Jordan Crouse 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.
