Hi Vinod, A small set of updates to the dma-jz4780 driver. It adds support for the MDMA/BDMA engines in the JZ4760(B) and JZ4770 SoCs, which are just regular cores with less channels. It also adds support for bidirectional channels, so that devices that only do half-duplex transfers can request a single DMA channel for both directions. Changes since V1 include: - indentation fixes in patch [1/6], - a better worded documentation in patch [2/6], - a new patch [5/6] to convert all uses of uint32_t to u32. You mentioned the fact that it would be great to have an exemple in the documentation file that uses #dma-cells = <3>. I will add one in a future patchset to the SD controller's binding documentation, when its driver will be updated to support bidirectional DMA channels.
