Subject: [PATCH 0/5] dmaengine: dma-jz4780: Driver updates

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.

Cheers,
-Paul
