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
