Can you please add documentation. Oh, the next patch is just adding the entry to the .dtsi file for the AHB, so no surprise it doesn't add a binding document for the SMMU! I see that with this patch, the driver still expects the DMA window to be represented as a reg property (IORESOURCE_MEM), so if we add a binding document to this patch it won't be very consistent either:-( And then, there's the issue of whether the SMMU should be it's own device or a child of some MC device, since there's non-SMMU functionality in these registers too. This makes all the SMMU rework need a little more thought. So, I propose dropping this patch from this series, since this series is all about adding the AHB driver. We should move this patch to a series relating to the SMMU driver. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
