Subject: [PATCH v2 0/6] dmaengine: jz4780: Driver updates v2

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.

Cheers,
-Paul
