[PATCH v1 03/10] dt-bindings: arm-smmu: add special case for Google Cheza platform

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

 



Cheza fw does not properly program the GPU aperture to allow the
GPU to update the SMMU pagetables for context switches. The board file
works around this by dropping the "qcom,adreno-smmu" compat string.
Add this usecase to arm,smmu.yaml schema.
