[PATCH 0/4] iommu/arm-smmu: Support Tegra234 SMMU

From: Thierry Reding <hidden>
Date: 2021-11-12 13:12:38

From: Thierry Reding <redacted>

Hi,

this series of patches adds and enables support for the ARM SMMU
instances found on the new Tegra234 SoC. This is mostly similar to what
can be found on Tegra194 except that there are a few more instances to
meet increased bandwidth needs.

In addition to adding support for the new Tegra234 compatible string,
this also adds a missing description for the nvidia,memory-controller
property to the ARM SMMU device tree binding.

I plan on picking up patch 4 into the Tegra tree because it has a
dependency (for the stream ID definitions) on a separate patch series
for the memory controller that I sent out earlier.

Thanks,
Thierry

[PATCH 1/4] dt-bindings: arm-smmu: Document nvidia,memory-controller property

From: Thierry Reding <hidden>
Date: 2021-11-12 13:12:41

From: Thierry Reding <redacted>

On NVIDIA SoC's the ARM SMMU needs to interact with the memory
controller in order to map memory clients to the corresponding stream
IDs. Document how the nvidia,memory-controller property can be used to
achieve this.

That's not a compatible change. Document why it is necessary if that's 
intended.

[PATCH 2/4] dt-bindings: arm-smmu: Add compatible for Tegra234 SOC

From: Thierry Reding <hidden>
Date: 2021-11-12 13:12:43

From: Thierry Reding <redacted>

The NVIDIA Tegra234 SoC comes with one single-instance ARM SMMU used by
isochronous memory clients and two dual-instance ARM SMMUs used by non-
isochronous memory clients.

Hi,

this series of patches adds and enables support for the ARM SMMU
instances found on the new Tegra234 SoC. This is mostly similar to what
can be found on Tegra194 except that there are a few more instances to
meet increased bandwidth needs.

In addition to adding support for the new Tegra234 compatible string,
this also adds a missing description for the nvidia,memory-controller
property to the ARM SMMU device tree binding.

Besides a nitpick about the inconsistent enum ordering in patch #2,

Acked-by: Robin Murphy <robin.murphy@arm.com>

for patches #1-3.

Cheers,
Robin.

I plan on picking up patch 4 into the Tegra tree because it has a
dependency (for the stream ID definitions) on a separate patch series
for the memory controller that I sent out earlier.

Thanks,
Thierry

Heh, yeah, I'll go fix that up so it's consistent in both the top-level
compatible property description and the conditionals.
