Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma
Pull second set of slave-dmaengine updates from Vinod Koul:
"Arnd's patch moves the dw_dmac to use generic DMA binding. I agreed
to merge this late as it will avoid the conflicts between trees.
The second patch from Matt adding a dma_request_slave_channel_compat
API was supposed to be picked up, but somehow never got picked up.
Some patches dependent on this are already in -next :("
* 'next' of git://git.infradead.org/users/vkoul/slave-dma:
dmaengine: dw_dmac: move to generic DMA binding
dmaengine: add dma_request_slave_channel_compat()
