2011/7/10 Sundaram Raju [off-list ref]:

Added new dma_ctrl_cmd TI_DMA_STRIDE_CONFIG to pass the TI DMA
controller specific configurations on how a buffer must be walked
through and how data is picked for transfer based on a specified
pattern over the channel.

The configuration passed is specific to the TI DMA controller used.
