Subject: [PATCH v10 0/5] NVIDIA ARM SMMU Implementation
Date: Tue, 7 Jul 2020 22:00:12 -0700 [thread overview]
Message-ID: <20200708050017.31563-1-vdumpa@nvidia.com> (raw)
Changes in v10:
Perform SMMU base ioremap before calling implementation init.
Check for Global faults across both ARM MMU-500s during global interrupt.
Check for context faults across all contexts of both ARM MMU-500s during context fault interrupt.
Add new DT binding nvidia,smmu-500 for NVIDIA implementation.
