NVIDIA Tegra20/30 SoC's have AHB DMA controller. It has 4 DMA channels, supports AHB <-> Memory and Memory <-> Memory transfers, slave / master modes. This driver is primarily supposed to be used by gpu/host1x in a master mode, performing 3D HW context stores.

Well, they are dependent in a sense of making driver usable. Only the "SCLK rate bump" patch isn't strictly needed. Splitting this series won't cause building failures, but all pieces should be in place for the working driver. So I suppose it is okay if clk patches would get in earlier than the others, I'll split the series. Thank you for the review. -- Dmitry
