typedef int32_t(*	MCSPI_dmaOpenFxn) (void *mcspiDmaArgs)
	Driver implementation to open a specific DMA driver channel - UDMA, EDMA etc. More...
typedef int32_t(*	MCSPI_dmaCloseFxn) (MCSPI_Handle handle, const MCSPI_ChConfig *chCfg)
	Driver implementation to close a specific DMA driver channel - UDMA, EDMA etc. More...
typedef int32_t(*	MCSPI_dmaChInitFxn) (MCSPI_Handle handle, const MCSPI_ChConfig *chCfg, const MCSPI_DmaChConfig *dmaChCfg)
	Driver implementation to init a DMA channel params using a specific DMA driver - UDMA, EDMA etc. More...
typedef int32_t(*	MCSPI_dmaTransferMasterFxn) (MCSPI_Object *obj, MCSPI_ChObject *chObj, const MCSPI_Attrs *attrs, MCSPI_Transaction *transaction)
	Driver implementation to do a DMA transfer using a specific DMA driver - UDMA, EDMA etc. More...
typedef int32_t(*	MCSPI_dmaStopFxn) (MCSPI_Object *obj, const MCSPI_Attrs *attrs, MCSPI_ChObject *chObj, uint32_t chNum)
