I rebased to both yours and Jassi by my merging manually. I remember you have changed the last param of device_prep_dma_cyclic from dma_data_direction to dma_transfer_direction. After checking the tree interleaved_dma @ git://git.infradead.org/users/vkoul/slave-dma.git, it doesn't. then make another compiling warning in sirfsoc_dma_prep_cyclic(). so I'll still use dma_data_direction in sirfsoc_dma_prep_cyclic().
