I noticed the same thing Stephen noticed earlier - I couldn't compile the driver. Other than that, there were a couple of differences to the tree we've worked with and tested earlier: Tegra30 support was dropped and as a consequence so was IOMMU support. I'm perfectly fine with leaving out IOMMU support, because we had some problems with that and dma-buf. We were getting a bit worried about how to implement mapping and re-mapping dma-buf's without causing duplicate IOMMU mappings. Best regards, Terje
