[PATCH v7 00/12] NVIDIA Tegra memory controller and IOMMU support
From: Thierry Reding tred...@nvidia.com This is the sixth installment in the Tegra IOMMU and memory controller support series. This version addresses the final outstanding comments from Olof about using proper Kconfig symbols to track the dependencies. It also splits up the driver into one part that implements the memory controller only and a second part that implements the SMMU. This plays nicely with the new Kconfig options introduced. Patch 1 is a preparatory patch that exposes the memory controller clock. Patches 2 and 3 is a pair of precursory patches needed to make this all work on 64-bit ARM in the future. The device tree binding for the Tegra memory controller is added in patch 4 and patch 5 is the bulk of the series that move the existing memory controller and IOMMU drivers into the new unified driver that supports Tegra30, Tegra114 and Tegra124. Patches 6, 7 and 8 add the DT nodes for the memory controller/IOMMU on Tegra30, Tegra114 and Tegra124. IOMMU support is enabled for the display controllers in patches 9, 10 and 11. This will allow the display controllers to have their memory accesses translated by the SMMU, which will enable non-contiguous buffers to be used for scan-out. Finally patch 12 also adds support for Tegra132. It is kept separate because none of the other Tegra132 patches have been merged yet, but I've included it here for completeness. Because the patches are rather intertwined, I'd like to merge them all via the Tegra tree. For that I'll need Acked-bys from Mike, Russell and Joerg on patches 1, 2 and 3, and 5, respectively.

Do you want me to bounce it to you directly?

The patch is rather long though, so something filtering it wouldn't be that surprising.
