With the generic dmaengine_pcm support the omap-cpm can be replaced with a much smaller wrapper. CPU DAI drivers can use the: int sdma_pcm_platform_register(struct device *dev, char *txdmachan, char *rxdmachan); To register the platform driver, txdmachan/rxdmachan is only needed to be provided if the DMA channel names are not standard tx/rx, like in case of McPDM, or the DAI is only capable of one audio direction (DMIC, HDMI). This patch only introduces the source file and changes to the Kconfig/Makefile, but does not change any of the DAI drivers to use it.
