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.
...and I suspect the slave device drivers that use TI DMA are not expected to ever work with other dmaengines? Likely the case, but just wondering out loud.
