OMAP: McBSP: APIs to pass DMA params from McBSP driver to client drivers
After McBSP driver is hwmod adapted, the information about the hw would be obtained from the hwmod database by the mcbsp driver. Since DMA programming is handled by the client driver, APIs are provided to pass the DMA channel number and base address of data register required by the client driver for DMA programming.
