I've had that in my tree for a little while as part of a small series that fixes up IOMMU usage (groups are really better for a number of reasons than directly attaching to devices), but kept forgetting to send it out.

> Subject: [PATCH] drm/nouveau: tegra: Use IOMMU groups
>
> Use IOMMU groups to attach the GPU to its IOMMU domain. This is not
> strictly necessary because the domain isn't shared with any other
> device, but it makes the code consistent with how IOMMU is handled in
> other drivers and provides an easy way to detect when no IOMMU has
> been attached via device tree.
