Slave-dma has become the predominant usage model for dmaengine and needs special attention. Memory-to-memory dma usage cases will continue to be maintained by Dan.

Several factors have contributed to the need to add a co-maintainer to dmaengine. First my time is being consumed in other areas [1]. Also, after Russell's review of amba-pl08x it became clear that the semantics of the slave interface need to specified [2]. My work on the iop-adma and ioatdma drivers has been limited to the memory-to-memory use cases (NET_DMA and ASYNC_TX_DMA). Without direct slave-dma api experience (client driver or dma driver) it is difficult to parse its needs outside of its base similarities with the memory-to-memory case.
I have asked my colleague, Vinod Koul, to: 1/ put more definition around the slave api and usages to try to ensure consistent behavior across drivers (as much as possible) 2/ help review and merge new drivers according to this definition
Vinod wrote the intel_mid_dma driver and expects to be involved with slave-dma for the foreseeable future.
I will continue to maintain the memory-to-memory and related async_tx usages of dmaengine (that need fixing [3]), but it is clear that this usage has become a secondary role for the dmaengine infrastructure.
